What is Maleic Acid?
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 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.
