  • Health Effects: Skin irritation if contacts skin, redness and itching of skin and eyes. Acute exposure may lead to coughing, shortness of breath, headache, nausea, vomiting. Chronic exposure can lead to damage of the blood, liver and CNS. Neurotoxicity can arise due to chronic exposure through inhalation or skin. Human cases of 1-bromopropane (1-BP) toxicity exhibit ataxic gait and cognitive dysfunction, whereas rat studies showed pyknotic shrinkage in cerebellar Purkinje cells and electrophysiological changes in the hippocampus. Inhalation exposure to 1-bromopropane causes skin tumors in male rats, large intestine tumors in female and male rats, and lung tumors in female mice. 1-bromopropane, either directly or via reactive metabolites, can cause molecular alterations that typically are associated with carcinogenesis, including genotoxicity, oxidative stress, and glutathione depletion. Hepatotoxicity and reproductive toxicity have been noted in rodent studies. Source: Toxin and Toxin Target Database (T3DB)

  • Toxicity Summary: IDENTIFICATION AND USE: 1-Bromopropane (1-BP) is a colorless liquid. 1-BP is used primarily as a solvent cleaner in vapor and immersion degreasing operations to clean optics, electronics, and metals and as a solvent vehicle in industries using aerosol-applied adhesives, such as foam cushion manufacturing. HUMAN STUDIES: Occupational exposure to 1-BP has been linked to neurological illnesses. Exposure to 1-BP could adversely affect peripheral nerves or/and the central nervous system. A 43-year-old male industrial worker developed muscle weakness, pain, numbness, and gait disturbance. Neurological examination indicated sensory ataxic neuropathy associated with mild impairment of upper motor neurons. He had used 1-BP as a cleaning agent for metal parts at his workplace without appropriate protection. Another case study reported that a 19-year-old male experienced weakness of the lower extremities and the right hand, numbness, and difficulty swallowing and urinating after 2 months of occupational exposure to a degreasing solvent based on 1-BP. 1-BP is cytotoxic but not corrosive, based on results from a cultured reconstructed human epidermal model (EpiDerm Skin Corrosivity Test). 1-BP Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: Organobromide compounds, especially alkylbromides are strong alkylating agents. Consequently they can randomly modify the surfaces of proteins and lipids, leading to the disruption of enzyme, transporter or membrane functions. Alkylation of DNA by alkylbromides may also lead to mutations. 1-bromopropane reacts quickly with hepatic glutathione (GSH) leading to its rapid depletion and subsequent liver damage. Long-term exposure to 1-bromopropane decreases neurogenesis in the dentate gyrus which may contribute to the neurotoxicity. Downregulation of brain derived neurotrophic factor and glucocoritoid receptor mRNA expression and low hippocampal norepinephrine levels might contribute, at least in part, to the reduced neurogenesis. Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 11 was calculated in fish for 1-bromopropane(SRC), using a measured log Kow of 2.10(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). 1-Bromopropane was classified as having low bioconcentration based on fish accumulation studies (specific data not reported)(4). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 37(SRC), determined from a structure estimation method(2), indicates that 1-bromopropane is expected to have very high mobility in soil(SRC). Volatilization of 1-bromopropane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.3X10-3 atm-cu m/mole(SRC) derived from a vapor pressure of 111 mm Hg(3) and water solubility of 2450 mg/L(4). 1-Bromopropane is expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC). A 70% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation may be an important environmental fate process in soil(SRC). A number of pure culture studies(6-9) have shown that microorganisms are capable of degrading 1-bromopropane. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 37(SRC), determined from a structure estimation method(2), indicates that 1-bromopropane is not 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 7.3X10-3 atm-cu m/mole(SRC), derived from a vapor pressure of 111 mm Hg(4) and water solubility of 2450 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 3.4 hours and 4.4 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 11(SRC), from its log Kow of 2.10(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). The hydrolysis half-life of 1-bromopropane is approximately 26 days at pH 7 and 25 °C(8). A 70% of theoretical BOD using activated sludge in the Japanese MITI test(9) suggests that biodegradation may be an important environmental fate process in water(SRC). A number of pure culture studies(10-13) have shown that microorganisms are capable of degrading 1-bromopropane. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-bromopropane, which has a vapor pressure of 111 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-bromopropane 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 15 days(SRC), calculated from its rate constant of 1.06X10-12 cu cm/molecule-sec at 25 °C(3). 1-Bromopropane does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

  • Uses: In the early to mid 1990s, 1-bromopropane was used primarily as an intermediate in the production of pesticides, quaternary ammonium compounds, flavors and fragrances, pharmaceuticals, and other chemicals in well-controlled, closed processes. In the mid to late 1990s, it was introduced as a less toxic replacement for methylene chloride in emissive applications such as vapor and immersion degreasing operations and critical cleaning of electronics and metals. 1-Bromopropane was also introduced as a nonflammable, nontoxic, fast-drying, and inexpensive solvent for adhesive resins, and has been marketed as a replacement for ozone depleting refrigerants.

Source: Hazardous Substances Data Bank (HSDB)
  • Uses: Cleaning solvent, drycleaning solvent, aerosol glue solvent. 1-bromopropane may be found in products used in vapor and immersion degreasing operations for cleaning metal, plastics, electronic and optical components; in adhesive spray applications; and in dry cleaning operations. 1-bromopropane may also be a component of some aerosol spray products. Exposures to 1-bromopropane in occupational settings occur via two primary routes: (1) inhalation of 1-bromopropane vapors and mists; and (2) skin contact with 1-bromopropane.
