Cannabis Compound Identification
Common NamePropanoic acid, anhydride
DescriptionPropanoic acid anhydride, also known as propanoic anhydride, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing two carboxylic acid groups. Propanoic anhydride is an organic compound with the formula (CH3CH2CO)2O. This simple acid anhydride is a colorless liquid with an intensively pungent odor. Propanoic anhydride is widely used in organic synthesis, particularly for the preparations of esters, as well as for producing specialty derivatives of cellulose. Propanoic anhydride is strong smelling and corrosive and can cause burns on contact with skin. Vapour can burn eyes and lungs. Due to its potential use as a precursor in the synthesis of fentanyl and fentanyl analogs, propanoic anhydride is regulated by the United States Drug Enforcement Administration as a List I chemical under the Controlled Substances Act. Propanoic acid anhydride has also been found in the volatile fraction of Cannabis sativa samples obtained from police seizures (PMID: 26657499 ).
