This type of acid is perfect for adding in salts with drugs so that they can become more stable, for example, indacaterol maleate. This conversion of maleic acid into fumaric acid does not take place instantaneously because to perform rotation around a C-C double bond is very difficult. In many industries to obtain maleic acid, hydrolysis of maleic anhydride is carried out. Now by removing bromine radical, For explaining the properties of maleic acid intramolecular It's considered an alpha-hydroxy acid, a class of natural acids commonly used in skin-care products. The anhydride moieties can subsequently be hydrolyzed to maleic acid (Figure \(\PageIndex{2}\)). Fumaric acid, methyl ester. Will likely be mobile in the environment due to its water solubility.
