Succinic Acid

Succinic acid is an alpha,-dicarboxylic acid resulting from the formal oxidation of each of the terminal methyl groups of butane to the corresponding carboxy group. It is an intermediate metabolite in the citric acid cycle. It has a role as a micronutrient, an anti-ulcer drug, a nutraceutical, a radiation protective agent and a fundamental metabolite. It is an alpha,omega-dicarboxylic acid and a C4-dicarboxylic acid. It is a conjugate acid of a succinate(1-). — ChEBI

  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) shou Source: CAMEO Chemicals

  • Health Effects: At acute doses or exposures succinic acid is a skin irritant. Chronically high doses of succinate can lead to succinylation or succination of a variety of enzymes. Partial succinate dehydrogenase deficiency (15% to 50% of normal reference enzyme activity) in skeletal muscle leads to elevated succinate levels and causes mitochondrial myopathy with various symptoms, for example, brain involvement, cardiomyopathy, and/or exercise intolerance.

  • Cosmetic Ingredient Review Finding(s): Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org Source: Cosmetic Ingredient Review (CIR)
  • Toxicity Summary: Succinate can inhibit the activities of α-KG–dependent oxygenases (KDMs) and the TET family of 5-methlycytosine (5mC) hydroxylases. Succinate also mediates allosteric inhibition of hypoxia inducible factor (HIF) prolyl hydroxylases (PHDs). Inhibition of HIF PHDs leads to activation of HIF-mediated pseudohypoxic response, whereas inhibition of KDMs and TET family of 5mC hydroxylases causes epigenetic alterations that ultimately cause cancer. Succination of KEAP1 in FH deficiency results in the constitutive activation of the antioxidant defense pathway mediated by NRF2, conferring a reductive milieu that promotes cell proliferation. Succination of the Krebs cycle enzyme Aco2 impairs aconitase activity in Fh1-deficient MEFs. Succination also causes irreversible inactivation of glyceraldehyde-3-phosphate dehydrogenase (GAPDH).

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for succinic acid (SRC), using a log Kow of -0.59(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentraion 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 11(SRC), determined from a log Kow of -0.59(2) and a regression-derived equation(3), indicates that succinic acid is expected to have very high mobility in soil(SRC). Volatilization of succinic acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.6X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 1.91X10-7 mm Hg(4), and water solubility, 8.32X10+4 mg/L(5). Succinic acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 1.91X10-7 mm Hg at 25 °C(4). The anion form, which is the dominant form in the environment (pKa 4.16 and 5.6), will also not volatilize(SRC). Succinic acid has been observed to biodegrade in soil at rates ranging from 52 to 89% in 7 days to 71 to 95% in 84 days at an initial concn of 1000 ppm(6), suggesting biodegration may be an important environmental fate process in soil.

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 11(SRC), determined from a log Kow of -0.59(2) and a regression-derived equation(3), indicates that succinic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.6X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 1.91X10-7 mm Hg(4), and water solubility, 8.32X1+4 mg/L(5). One of the pKa values of succinic acid is 4.21(6), indicating that this compound will exist in the dissociated form in the environment and anions generally do not adsorb more strongly to suspended solids and sediment than their neutral counterparts(7), and will not volatilize. According to a classification scheme(8), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Succinic acid, present at 100 mg/L, reached 78% of its theoretical BOD in 14 days using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(10), suggesting biodegradation may be an important environmental fate process in 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), succinic acid, which has a vapor pressure of 1.91X10-7 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase succinic 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 6 days(SRC), calculated from its rate constant of 2.8X10-12 cu cm/molecule-sec at 25 °C that was derived using a structure estimation method(3). Particulate-phase succinic acid may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
