IDENTIFICATION AND USE: Amyl mercaptan is a liquid. It is used as an intermediate in the synthesis of organic sulfur compounds and as a synthetic flavoring agent. It is the chief constituent of the odorant used in gas lines to locate leaks. HUMAN STUDIES: Potential symptoms of overexposure include headache, nausea, dizziness, vomiting, diarrhea, dermatitis, skin sensitization, and irritation of eyes, skin, nose, throat, and respiratory system. ANIMAL STUDIES: No skin irritation was reported in rabbits after a 24 hr exposure, but marked eye irritation in rabbits lasted for 3 days. A range-finding study found inhalation of 2000 ppm for 4 hr killed two to four rats out of six exposed. In rats, amyl mercaptan produced stomach ulcers and adrenal gland damage at dosages that cause 70-100% mortality in 5 days.

n-Amyl mercaptan is reported to be found in nature(1).|Small quantities /of n-amyl mercaptan/ occur in natural gas deposits with crude oil or in decaying animal or plant tissue.

n-Amyl mercaptan's production and use as an intermediate in the synthesis of organic sulfur compounds and synthetic flavoring agent(1,2) may result in its release to the environment through various waste streams(SRC). Its use as an odorant used in gas lines to locate leaks(1,2) will result in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a structure estimation method(2), indicates that n-amyl mercaptan is expected to have moderate mobility in soil(SRC). Volatilization of n-amyl mercaptan from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.2X10-2 atm-cu m/mole(SRC), based upon its vapor pressure, 13.8 mm Hg(3), and water solubility, 156 mg/L(4). n-Amyl mercaptan is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Biodegradation data in soil were not available(SRC, 2018).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a structure estimation method(2), indicates that n-amyl mercaptan is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 1.2X10-2 atm-cu m/mole(SRC), derived from its vapor pressure, 13.8 mm Hg(4), and water solubility, 156 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3 hours and 4 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 30(SRC), from an estimated log Kow of 2.74(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low to moderate(SRC). Biodegradation data in water were not available(SRC, 2018).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-amyl mercaptan, which has a vapor pressure of 13.8 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-amyl mercaptan 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 8 hrs(SRC), calculated from its rate constant of 4.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). n-Amyl mercaptan absorbs UV light at wavelength 210 nm(4) and, therefore, is not expected to be susceptible to direct photolysis since sunlight consists of wavelengths above 290 nm(SRC).

The rate constant for the vapor-phase reaction of n-amyl mercaptan with photochemically-produced hydroxyl radicals has been estimated as 4.56X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 8 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). n-Amyl mercaptan is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2). n-Amyl mercaptan absorbs UV light at wavelength 210 nm(3) and, therefore, is not expected to be susceptible to direct photolysis since sunlight consists of wavelengths above 290 nm(SRC).

An estimated BCF of 30 was calculated in fish for n-amyl mercaptan(SRC), using an estimated log Kow of 2.74(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low to moderate(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-amyl mercaptan can be estimated to be 130(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-amyl mercaptan is expected to have high mobility in soil(SRC).

The Henry's Law constant for n-amyl mercaptan is estimated as 1.2X10-2 atm-cu m/mole(SRC) derived from its vapor pressure, 13.8 mm Hg(1), and water solubility,156 mg/L(2). This Henry's Law constant indicates that n-amyl mercaptan is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 3 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 8 days(SRC). n-Amyl mercaptan's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of n-amyl mercaptan from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

Reported Uses: baked goods, 0.8 ppm; breakfast cereals, 0.8 ppm; fats, oils, 0.04 ppm; milk products, 0.8 ppm; meat products, 0.8 ppm; confection, frosting, 0.8 ppm; soups, 0.8 ppm; nonalcoholic beverages, 0.8 ppm.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 28 workers are potentially exposed to n-amyl mercaptan in the US(1). Occupational exposure to n-amyl mercaptan may occur through inhalation and dermal contact with this compound at workplaces where n-amyl mercaptan is produced or used. Use data suggest that the general population may be exposed via ingestion of foods containing n-amyl mercaptan as a flavoring(SRC).

Inhalation may cause nausea because of offensive odor. Contact with eyes or skin causes slight irritation. Ingestion may cause vomiting. (USCG, 1999)
