Maleic acid CAS 110-16-7

Maleic acid, or maleic acid, is a dicarboxylic acid, i.e., an organic compound containing two carboxylic acid functional groups. Maleic acid and transbutylene dicarboxylic acid (fenugreek) are cis-trans isomers of each other. Maleic acid is commonly used in the preparation of transbutylene dicarboxylic acid, and the anhydride of maleic acid is maleic anhydride, which has fewer applications compared to its anhydride.
