Product Description

Product Description

 

Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. It may be used to form acid addition salts with drugs to make them more stable, such as indacaterol maleate. Maleic acid is also used in manufacturing synthetic resins; in textile processing; in preserving oils and fats; to retard rancidity of fats and oils in 1:10,000 (these are said to keep 3 times longer than those without the acid); dyeing and finishing wool, cotton, and silk; preparing the maleate salts of antihistamines and similar drugs.
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.
