High quality Maleic Acid (cis-butenedioic acid/toxilic acid),CAS No.:110-16-7
Maleic acid is is an organic acid, known as cis-butenedioic acid, toxilic acid, cis-1,2-Ethylenedicarboxylic acid. CAS:110-16-7
Maleic acid is soluble in water, whereas fumaric acid is not; and the melting point of maleic acid (130 - 139 °C) is also much lower than that of fumaric acid (287 °C).
USE:
It is mainly used for making Maleate Salts of Bulk-Drugs like Pheneramine Maleate, Chloropheneramine Maleate and others. It is also used to prevent rancidity in oils.
