    Maleic acid - Wikipedia

    Maleic acid or cis-butenedioic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. Its chemical formula is HO 2 CCH=CHCO 2 H. Maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer.It is mainly used as a precursor to fumaric acid, and relative to its parent maleic anhydride, maleic acid has few applications.
