  • NFPA Health Rating: 1 - Materials that, under emergency conditions, can cause significant irritation. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Fire Rating: 2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF value of 13 was calculated for 2-octanone(SRC), using a log Kow of 2.37(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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 460(SRC), determined from a log Kow value of 2.37(2) and a regression-derived equation(3), indicates that 2-octanone is expected to have moderate mobility in soil(SRC). Aerobic biodegradation of this compound is expected. 2-Octanone, inoculated with acclimated sludge, had BOD values from 33%(4) to 48%(5,6) of the theoretical oxygen demand after 5 days incubation. Volatilization of 2-octanone from moist soil surfaces in expected to be an important fate process(SRC) given a Henry's Law constant of 1.88X10-4 atm-cu m/mole(7). 2-Octanone is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.35 mm Hg(8). Theoretical BOD values of 33%(8) and 48%(9) suggest that biodegradation may occur in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 460(SRC), determined from a log Kow value of 2.37(2) and a regression-derived equation(3), indicates that 2-octanone is expected to adsorb to suspended solids and sediment(SRC). In water, 2-octanone has a measured volatilization flux of 40 g/min/sq m; some attenuation of this process is expected due to the gas-film interface(4). A measured Henry's Law constant of 1.88X10-4 atm-cu m/mole(5) also indicates that this compound will volatilize from water surfaces. Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 5 hours and 6 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 13(SRC), from its log Kow(2), and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low. 2-Octanone is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Theoretical BOD values of 33%(8) and 48%(9,10) suggest that biodegradation may occur in water(SRC). 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), 2-octanone, which has a vapor pressure of 1.35 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-octanone 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 1.6 days(3). 2-Octanone does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
