  • Toxicity Summary: IDENTIFICATION AND USE: Diethyl malonate is used in chemical synthesis. It is also used in food, beverages, and in fragrances. HUMAN STUDIES: A maximization test was reported in 23 volunteers. 4% of the test substance in petrolatum produced no sensitization reactions. Tested at 4% in petrolatum it produced no irritation after a 48-hr closed-patch test on human subjects. ANIMAL STUDIES: Diethyl malonate causes moderate irritation to rabbit's eyes and is non-irritating to rabbit's skin. Application of 0.005 mL of undiluted diethyl malonate to the rabbit cornea caused severe burning. Diethyl malonate fed to rats for 90 days at more than 100 times the equivalent of the human daily dietary intake (averaging 35.93 mg/kg bw per day for males and 41.14 mg/kg bw per day for females) had no adverse effects. The maximum time for inhalation of the concentrated vapor of diethyl malonate by rats without deaths was found to be 8 hr. Mutagenicity test in Salmonella typhimurium TA98, TA 100, TA 1535, TA 1537, TA 1538 was negative with and without activation at concentrations of 8, 40, 200, 1000, 5000 ug/plate 5000 ug/plate (maximal concentration).

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for diethyl malonate(SRC), using a log Kow of 0.96(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 10(SRC), determined from a structure estimation method(2), indicates that diethyl malonate is expected to have very high mobility in soil(SRC). Volatilization of diethyl malonate from moist soil surfaces may occur(SRC) given an estimated Henry's Law constant of 2.0X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 0.19 mm Hg(3), and water solubility, 2.0X10+4 mg/L(4). In chemical stimulant studies simulating chemical warfare agents, diethyl malonate deposited to dry soil and foliar surfaces was rapidly lost through volatilization processes with observed half-lives on soil of about 2 hours (fast) to 5-16 hours (residual material)(4); foliar half-lives ranged from 1 to 242 hours(5). Two screening studies found diethyl malonate to be readily biodegradable(6,7). An 86% of theoretical BOD in two weeks using activated sludge in the Japanese MITI test(6) suggests that 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 10(SRC), determined from a structure estimation method(2), indicates that diethyl malonate 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 2.0X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 0.19 mm Hg(4), and water solubility, 2.0X10+4 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 23 and 173 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow of 0.96(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Two screening studies found diethyl malonate to be readily biodegradable(8,9). An 86% of theoretical BOD in two weeks using activated sludge in the Japanese MITI test(8) suggests that biodegradation is an important environmental fate process in water(SRC). Diethyl malonate hydrolyzes readily in neutral and alkaline water, but slowly in acidic water(10). Respective hydrolysis h 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), diethyl malonate, which has a vapor pressure of 0.19 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethyl malonate 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 3.1 days(SRC), calculated from its rate constant of 3.4X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Diethyl malonate contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
