| Hazards summary | Dimethylcarbamoyl chloride is used as an intermediate in the production of pharmaceuticals, pesticides, and dyes. Acute (short-term) inhalation exposure to dimethylcarbamoyl chloride has been observed to result in damaged mucous membranes of the nose, throat, and lungs, and cause difficulty in breathing in rats. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic health effects of dimethylcarbamoyl chloride in humans. Nasal tract carcinomas have been observed in rats and male hamsters following inhalation exposure. EPA has not classified dimethylcarbamoyl chloride for potential carcinogenicity.Liquid causes second or third degree burns after short contact. [CHRIS] A lachrymatorInhalation exposure to HCl may cause chemical pneumonitis[HSDB] DMCC reacts with tissue at the point of contact. DMCC hydrolyzes to dimethylamine, CO2, and HCl. Animals in feeding studies develop liver hemorrhages. Sprague-Dawley rats were exposed by inhalation 6 hours/day, 5 days/week for 6 weeks at 0.5, 1.0, or 2.0 ppm DMCC in an exposure chamber and held without further exposure for up to 2 years. A dose-response relationship for both the development of morphological lesions and for tumor incidences of the nasal cavity and nasopharyngeal areas was seen, ranging from 89% tumor incidence at 2 ppm to 4% incidence at 0.5 ppm. No tumors in these regions were reported in the controls. [ACGIH] |

| Special Reports | National Toxicology Program. Eleventh Report on Carcinogens (2005). The Report on Carcinogens is an informational scientific and public health document that identifies and discusses substances (including agents, mixtures, or exposure circumstances) that may pose a carcinogenic hazard to human health. Dimethylcarbamoyl Chloride (79-44-7) is listed as reasonably anticipated to be a human carcinogen.[Available from, as of July 31, 2009: http://ntp.niehs.nih.gov/ntp/roc/eleventh/profiles/s076dime.pdf] |
| RCRA requirements | U097As stipulated in 40 CFR 261.33, when dimethylcarbamoyl chloride, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). |
| Reactivity Alerts | Water-Reactive |
| Reactivity Profile | DIMETHYLCARBAMOYL CHLORIDE is water reactive. Incompatible with strong oxidizing agents, alcohols, bases (including amines). May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Gives toxic fumes of NOx and HCl when burned (USCG, 1999). |

| Environmental fate | TERRESTRIAL FATE: If dimethylcarbamoyl chloride is released to soil, it will be expected to rapidly hydrolyze if the soil is moist, based upon a half-life of 54 sec at 14 °C(SRC) calculated from a measured hydrolysis rate constant(1). Since it rapidly hydrolyzes, adsorption to and volatilization from moist soil are not expected to be significant processes, although no data specifically regarding the fate of dimethylcarbamoyl chloride in soil were located(SRC). The potential for volatilization of dimethylcarbamoyl chloride from dry soil surfaces may exist(SRC) based upon a vapor pressure of 1.95 mm Hg(2). Biodegradation should not be an important process since hydrolysis is such a rapid process(SRC).AQUATIC FATE: If dimethylcarbamoyl chloride is released to water, it will be expected to rapidly hydrolyze, based upon a half-life of 54 sec at 14 °C(SRC) calculated from a measured hydrolysis rate constant(1). The products of hydrolysis are dimethylamine, carbon dioxide, and hydrogen chloride(2). Since it rapidly hydrolyzes, bioconcentration, volatilization, and adsorption to sediment and suspended solids are not expected to be significant processes(SRC). No data were located concerning biodegradation, but dimethylcarbamoyl chloride probably abiotically degrades via hydrolysis significantly faster than via biodegradation(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dimethylcarbamoyl chloride, which has a vapor pressure of 1.95 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase dimethylcarbamoyl chloride is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 24 hours(SRC), calculated from its rate constant of 16X10-12 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). The hydrolysis half-life for dimethylcarbamoyl chloride is 54 sec(SRC), calculated from its rate constant of 12.76X10-3 sec-1(4), which suggests that vapor-phase dimethylcarbamoyl chloride will rapidly hydrolyze in fog and rain(SRC). |

| Artificial Pollution Sources | Dimethylcarbamoyl chloride's production and former use as a chemical intermediate in the production of dyes, pharmaceuticals, and pesticides(1) may have resulted in its release to the environment through various waste streams(SRC). |
| Atmospheric standards | Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants.

Dimethyl carbamoyl chloride is included on this list. |
