What is Maleic Acid?

Maleic Acid is also known as cis-butenedioic acid, toxilic acid, cis-1,2-Ethylenedicarboxylic acid. It is commercially available as the crystalline material or as an aqueous solution in water (40%). It may contain fumaric acid (0.1%) and water (less than 0.5%) as impurities.

Uses : 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.

Various Applications of Maleic Acid:

Maleic acid is not very important economically, since the anhydride is easier to use. It is employed in the manufacture of phthalic-type alkyd and polyester resins, surface coatings, copolymers, plasticizers, lubricant additives and agricultural chemicals; in adhesives and sealants; as a preservative for oils and fats; organic synthesis; dyeing and finishing wool, cotton and silk; and preparing the maleate salts of antihistamines and similar drugs.
