This compound is not very flammable but any fire involving this compound may produce dangerous vapors. You should evacuate the area. All firefighters should wear full-body protective clothing and use self-contained breathing apparatuses. You should extinguish any fires involving this chemical with a dry chemical, carbon dioxide, foam, or halon extinguisher. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Use water spray, carbon dioxide, dry chemical, or "alcohol" foam. Use water to keep fire-exposed containers cool. If leak or spill has not ignited, use water spray to disperse vapors and to protect men attempting to stop leak.

Water spray may be used to flush spills away from exposures and to dilute spills to nonflammable mixtures.

Personnel protection: Wear self-contained breathing apparatus.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 600(SRC), determined from a log Kow of 2.57(2) and a regression-derived equation(3), indicates that ethyl anthranilate is expected to have low mobility in soil(SRC). Volatilization of ethyl anthranilate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.6X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Ethyl anthranilate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.3X10-3 mm Hg(SRC), determined from a fragment constant method(5). Biodegradation data were not available(SRC, 2007).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 600(SRC), determined from a log Kow of 2.57(2) and a regression-derived equation(3), indicates that ethyl anthranilate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.6X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Hydrolysis is expected to be a slow environmental fate process; estimated second order hydrolysis half-lives are 5.8 years and 210 days at pH values of 7 and 8, respectively(5). According to a classification scheme(6), an estimated BCF of 19(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not available(SRC, 2007).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethyl anthranilate, which has an estimated vapor pressure of 2.3X10-3mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl anthranilate 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 11 hours(SRC), calculated from its rate constant of 3.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Ethyl anthranilate does absorb light at UV max of 330 nm(4) and therefore may be susceptible to direct photolysis by sunlight.

The Koc of ethyl anthranilate is estimated as 600(SRC), using a log Kow of 2.57(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethyl anthranilate is expected to have low mobility in soil.

An estimated BCF of 19 was calculated in fish for ethyl anthranilate(SRC), using a log Kow of 2.57(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The Henry's Law constant for ethyl anthranilate is estimated as 1.6X10-8 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that ethyl anthranilate is expected to be essentially nonvolatile from water surfaces(2). Ethyl anthranilate's Henry's Law constant indicates that volatilization from moist soil surfaces may not occur(SRC). Ethyl anthranilate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.3X10-3 mm Hg(SRC), determined from a fragment constant method(3).

/GENOTOXICITY/ Ethyl anthranilate was tested for mutagenicity in the Salmonella/ microsome preincubation assay using the standard protocol approved by the National Toxicology Program. Ethyl anthranilate was tested at doses of 0.01, 0.033, 0.10, 0.33, 0.50, and 0.80 mg/plate in as many as 5 Salmonella typhimurium strains (TA 1535, TA 1537, TA 97, TA 98, and TA 100) in the presence and absence of rat or hamster liver S-9. Ethyl anthranilate was negative in these tests and the highest ineffective dose tested without significant toxicity in any S. typhimurium strain was 0.33 mg/plate. Total clearing of the background bacterial lawn occurred in nearly all cultures tested at doses above this level.

/OTHER TOXICITY INFORMATION/ Listed in FDA's Food Additive Database as a chemical for which fully up-to-date toxicology information has been sought.

The rate constant for the vapor-phase reaction of ethyl anthranilate with photochemically-produced hydroxyl radicals has been estimated as 3.6X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 11 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A base-catalyzed second-order hydrolysis rate constant of 3.8X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(2); this corresponds to half-lives of 5.8 years and 210 days at pH values of 7 and 8, respectively(2). Ethyl anthranilate does absorb light at UV max of 330 nm(3) and therefore may be susceptible to direct photolysis by sunlight.
