Description

CAS: 110-16-7 | C4H4O4 | 116.07 g/mol

Maleic acid is 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
