Used in the preparation of tris-maleate buffer and sodium maleate buffer. It has also been used for the pretreatment of poplar tracheid cell walls for the spectroscopic analysis of lignin. It may be used to synthesize super swelling acrylamide/maleic acid hydrogels. Used as a precursor to fumaric acid, dimethyl maleate and glyoxalic acid. It is an electrophile and acts as dienophine in Diels-Alder reactions. It reacts with drugs to form more stable addition salts like indacaterol maleate, carfenazine, chlorpheniramine, pyrilamine, methylergonovine and thiethylperazine. Its maleate ion is useful in biochemistry as an inhibitor of transaminase reactions.
