Nonanoic Acid
Nonanoic acid is a C9 straight-chain saturated fatty acid which occurs naturally as esters of the oil of pelargonium. Has antifungal properties, and is also used as a herbicide as well as in the preparation of plasticisers and lacquers. It has a role as an antifeedant, a plant metabolite, a Daphnia magna metabolite and an algal metabolite. It is a straight-chain saturated fatty acid and a medium-chain fatty acid. It is a conjugate acid of a nonanoate. It derives from a hydride of a nonane. — ChEBI

- Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for nonanoic acid(SRC), using a log Kow of 3.42(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). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,700 for the free acid(SRC), determined from a log Kow of 3.42(2) and a regression-derived equation(3), indicates that undissociated nonanoic acid is expected to have low mobility in soil(SRC). The pKa of nonanoic acid is 4.95(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of nonanoic acid from moist soil surfaces is not expected to be an important fate process(SRC) given the pKa. Nonanoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.65X10-3 mm Hg(6). Biodegradation studies of nonanoic acid show a total organic carbon removal ratio of 99% using a non-acclimated activated sludge(7), and a BOD of 0.59 (g/g) after 5 days incubation using a sewage inoculum(8), suggesting biodegradation is an important environmental fate process in soil(SRC).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,700 for the free acid(SRC), determined from a log Kow of 3.42(2) and a regression-derived equation(3), indicates that undissociated nonanoic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 4.95(4) indicates nonanoic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation studies of nonanoic acid show a total organic carbon removal ratio of 99% using a non-acclimated activated sludge(8), and a BOD of 0.59 (g/g) after 5 days incubation using a sewage inoculum(9), suggesting biodegradation is an important environmental fate process 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), nonanoic acid, which has a vapor pressure of 1.65X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase nonanoic acid 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(SRC), calculated from its rate constant of 9.8X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Nonanoic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
