| Reactivity Alerts | Water-Reactive |
| Reactivity Profile | CYANURIC CHLORIDE reacts rapidly and exothermically with water to generate hydrogen chloride. A mixture with water in an industrial reactor with refrigeration turned off developed pressure that blew gaskets and filled the building with flammable vapors. An explosion occurred when the vapors were ignited [MCA Case History 1869(1972)]. Runaway reactions have occurred with acetone/watermethanol/water, ethoxyethanol/water, allyl alcohol/sodium hydroxide/water, 2-butanone/sodium hydroxide/water, and methanol/sodium bicarbonate [Loss Prev. Bull., 1979, (25), 21]. Reacts with methanol to give gaseous methyl chloride. Reacts rapidly with bicarbonates to generate gaseous carbon dioxide. Reacts vigorously with dimethyl formamide (DMF) to form carbon dioxide after a deceptive induction period [BCISC Quart. Safety Summ., 1960, 35, 24]. Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). |

| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a structure estimation method(2), indicates that cyanuric chloride will have high mobility in soil(SRC). Volatilization of cyanuric chloride from moist soil surfaces(SRC) is not expected to be an important environmental fate process given an estimated Henry's Law constant of 4.9X10-7 atm-cu m/mole(SRC), derived using a fragment constant estimation method(3). Volatilization from dry soil surfaces is not expected(SRC), based on an estimated vapor pressure of 0.023 mm Hg(SRC), derived from a structure estimation method(4). Complete anaerobic degradation of 250-500 uM of cyanuric chloride solutions incorporated into a methanogenic aquifer slurry was observed after a one year time period(5)however, cyanuric chloride hydrolyzes rapidly(6) and the degradation was likely due to hydrolytic dehalogenation rather than biodegradation(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a structure estimation method(2), indicates that cyanuric chloride is unlikely to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.9X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF value of 2(SRC), from an estimated log Kow of 1.73(6), and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). cyanuric chloride hydrolyzes rapidly in water(8). Approximately 40% degradation was observed in 1 hour at a temperature of 30 °C(8). Complete anaerobic degradation of 250-500 uM of cyanuric chloride solutions incorporated into a methanogenic aquifer slurry was observed after a one year time period(9)however, the degradation was likely due to abiotic (hydrolysis) rather than biotic (microbial) processes(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), cyanuric chloride, which has an estimated vapor pressure of 0.023 mm Hg at 25 °C(SRC), determined from a fragment constant estimation method(2), will exist solely as a vapor in the ambient atmosphere. Vapor phase cyanuric chloride is degraded slowly in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be about 4,300 days(SRC), calculated from its rate constant of 3.7X10-15 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). |

Clinical findings included a dose-related increased in hypoactivity, ruffled fur, labored breathing, muscular weakness, lacrimation, and prostration. Necropsy findings revealed severe chemical burns in the stomach lining, duodenum, and the lobe of the liver adjacent to the stomach. The animal dosed with 300 mg/kg revealed necrotic tissue in the stomach lining. The test substance was determined to be slightly to moderately toxic. The LD50 was determined to be greater than 300 mg/kg and less than 1000 mg/kg.Cyanuryl chloride (CAS# 108-77-0) was evaluated for acute inhalation toxicity. The test substance was administered via inhalation to male and female albino rats of the Tif: RAIf (SPF) strain for 4-hours. Concentration levels and mortality data are as follows: 0.0 (0/10 M, 0/10 F)5.0 (0/9 M, 0/9 F)7.0 (0/9 M, 0/9 F)18.4 (1/9 M, 0/9 F)40.5 (6/9 M, 0/9 F)108 (9/9 M, 6/9 F)and 495 mg/m3 (9/9 M, 9/9 F). Clinical signs included a dose-related increase in dyspnea, chromodacryorrhea, rhinorrhea, cyanosis, diarrhea, tremors and ruffled fur as well as lateral, ventral, and curved body position. A significant decrease in body weights was noted in both sexes at 40.5 mg/cu m, and depressed body weights and weight gains at 108 mg/cu m. Pathological findings revealed an area of discoloration of the lungs in all exposure groups. At 40.5 mg/cu m, enlarged or edematous lungs in 6/9 males was present, and similar findings were noted in 7/9 males and 6/9 females in the 495 mg/cu m group. Also noted was dilation of the stomach in 1 male in the 108 mg/cu m groups and 1 animal of each sex in the 495 mg/cu m group. The LC50 for males was 35 mg/cu m, and for females was 88 mg/cu m. The test substance was determined to be very toxic when administered to rats by the inhalation route.Cyanuryl chloride (CAS# 108-77-0) was evaluated for subchronic oral toxicity. The test substance was administered by oral gavage to Charles River CD albino rats for 5-days. Dosage levels and mortality data are as follows: 0 (0/5 M, 0/5 F)10 (0/5 M, 0/5 F)20 (0/5 M, 0/5 F)40 (0/5 M, 1/5 F)80 (2/5 M, 4/5 F)160 (4/5 M, 4/5 F)and 320 mg/kg/day (5/5 M, 5/5 F). Clinical signs at 20 mg/kg/day included rales, excessive salivation and/or gasping. At 40 mg/kg/day and above, toxicity consisted of rales, excessive salivation, labored breathing, gasping, cool to touch, decreased motor activity, brown material around mouth/nose, and moist areas of yellow material. At 20 mg/kg/day and above, a significant reduction in body weights and food consumption was noted for all rats. Pathological findings at 20 mg/kg/day and above, included lesions consisting of a dark discoloration, hemorrhages, erosions, and/or ulcerations in the glandular and nonglandular areas of the stomach.Cyanuric chloride (108-77-0) was evaluated for developmental effects in groups of 25 female Charles River rats exposed to the test substance by gavage on days 6 through 19 of gestation at dose levels of 0, 5, 25, and 50 mg/kg/day. All rats survived to sacrifice on day 20 except one animal at 25 mg/kg/day which died due to an intubation error. Animals at 50 mg/kg/day showed a slight decrease in group mean maternal body weight gain when compared to controls. The high dose group showed a significantly lower value for viable fetus/dam than the control group. Treatment had no affect on the incidence of malformations or developmental variations in any of the treated groups when compared with the control group. |
| Human Toxicity Excerpts | /HUMAN EXPOSURE STUDIES/ In human volunteers, the 1-min threshold irritation effect of inhaled cyanuric chloride was found to be 0.3 mg/cu m./SIGNS AND SYMPTOMS/ ...HAS SEVERE IRRITANT EFFECT ON EYES & RESP PASSAGES, BUT LESS EFFECT ON SKIN. SENSITIVITY & CHRONIC ECZEMA HAVE BEEN OBSERVED./CASE REPORTS/ Cyanuric chloride is a lachrymator and an irritant to the eyes and nose. Exposure of a laboratory assistant to a small amount of vapor resulted in rash on the neck and behind the ears with irritation./CASE REPORTS/ An, in general, healthy male (age 54) was exposed to cyanuric chloride during an inspection in a factory where herbicides were produced. Cyanuric chloride (one of the basic materials) was accidentally released, because a vessel got broken. The man was totally submerged under the powder. Signs of intoxication consisted of irritation of the skin, eyes and pharynx, followed by serious obstructive pulmonary syndrome with impairment of alveolar capillary exchanges. No effects on the heart function were seen (although a slightly abnormal ECG was reported from an pre-exposure investigation). The man recovered within 20 days./BIOMONITORING/ 39 workers with known history of long-term exposure to cyanuric chloride (between 1 and 22 years) were investigated. Investigations included anamnesis, physical examination (with special attention to lungs, skin and eyes), lung function (forced expiratory volume) and blood pressure measurements. Medical records of another 21 workers previously exposed to incidental high concentrations, who had changed jobs in the mean time, were checked. Determination of concentrations at the workplace. Samples (30-60 min) were taken during the filling procedure (worst case) and during normal production procedures (both room and personal monitoring). The samples were analyzed after adsorption tosilicagel, desorption with H2SO4, hydrolysis to cyanuric acid (70 min at 70 °C) and analysis of the cyanuric acid by HPLC with UV detection. No effects on any of the measured parameters were found. FEV was within normal ranges. Accidental acute exposure to high doses of cyanuric chloride was reported to lead to irritation/corrosion of the conjunctiva and skin irritation. After inhalation of the test substance coughing, breathing problems and shortness of breath were seen. These effects disappeared completely after a short time and did not result in persisting problems. Measured concentrations were 7.09 = or - 9.22 ug/cu m, 4.43 = or - 2.72 ug/cu m and 92.76 = or - 147.52 cu m, for filling, room and personal monitoring, respectively. |
| Artificial Pollution Sources | Cyanuric chloride's production and use as a precursor in the synthesis of herbicides and insecticides, optical brighteners, dyes, and plastics(1) may result in its release to the environment through various waste streams(SRC). |
| Environmental Biodegradation | ANAEROBIC: Complete anaerobic degradation of 250-500 uM cyanuric chloride solutions incorporated into a methanogenic aquifer slurry was observed after a one year time period(1). |
| Environmental Bioconcentration | An estimated BCF of 2 was calculated in fish for cyanuric chloride(SRC), using an estimated log Kow of 1.73(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests the potential for bioconcentration in aquatic organisms is low(SRC). Cyanuric chloride hydrolyzes rapidly in water(4), thus eliminating bioconcentration as an important environmental fate property. |
| Volatilization from Water/Soil | The Henry's Law constant for cyanuric chloride is estimated as 4.9X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that cyanuric chloride is not expected to volatilize from water surfaces or moist soil surfaces(2). Moreover, cyanuric chloride hydrolyzes rapidly in water(3), thus eliminating volatilization as an important environmental fate property. Cyanuric chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.023 mm Hg(SRC), determined from a fragment constant method(4). |
| 대기 기준 | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Cyanuric chloride is produced, as an intermediate or a final product, by process units covered under this subpart. |
