DescriptionECHEMI Editorial ReferenceDehydroacetic acid is an organic compound, classified as a pyrone derivative and is used mostly as a fungicide and bactericide.
Dehydroacetic acid is a pyran-2,4-dione substituted at position 3 by an acetyl group and at position 6 by a methyl group. A fungicide and bactericide it is used primarily in processed fruit and vegetables. It has a role as a fungicide, an antibacterial agent and a plasticiser. It is a pyran-2,4-dione and a ketone.
Dehydroacetic acid is an obsolete fungicide. It is highly soluble in water and is also a volatile substance. Ecotoxicological data is scarce. Dehydroacetic acid is moderately toxic to mammals via the oral route, is a neurotoxin and irritant.
Dehydroacetic acid is a white to cream-coloured powder that is only very slightly soluble in water (less than 0.1 %). However, the sodium salt hydrate (CSH7Na04.H20) has a solubility of 33% in water at 25°C, and 48% in propylene glycol. The acid is 22% soluble in acetone, 18% in benzene, and I g dissolves in about 35 ml of ethanol.It is used to reduce pickle bloating, and as a pesticide and preservative for squash and strawberries. Its permissible use level is 65ppm.Dehydroacetic acid is one of the food additives found in red wine and was determined by ultra-fast liquid chromatography-tandem quadrupole mass spectrometry (UFLC-MS/MS).To assay dehydroacetic acid, add 500 mg to a 250-ml Erlenmeyer flask and dissolve in 75 ml of neutral alcohol. Following the addition of phenolphthalein T.S., titrate with 0.1 N NaOH to a pink end-point that persists for at least 30 s. Each ml of 0.1 N NaOH = 16.82 mg of dehydroacetic acid (National Academy of Sciences, 1963).Dehydroacetic acid is a synthetic chemical (no plant-based preservatives that meet our efficacy standards currently exist) that is considered to be a low hazard for human health and for the environment.
Dehydroacetic acid is a pyrone derivative, that is typically synthesized by the base-catalyzed dimerization of diketene. It is used as a preservative in pharmaceutical, food and cosmetic products.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.CertificatesBasic Info-
