p-Aminobenzoic acid by MP Biomedicals is a high grade reagent. Also known as 4-Aminobenzoic acid and PABA, this is a naturally occurring organic compound which consists of a benzene ring substituted with amino and a carboxyl groups. This reagent is available as a white powder which is soluble in water, alcohol, ether, ethyl acetate, glacial acetic acid, warm glycerine, alkali hydroxides and carbonates, and is slightly soluble in benzene, chloroform. Industrially, it may be produced by the reduction of 4-nitrobenzoic acid, hoffman degradation of the monoamide derived from terephthalic acid.

p-Aminobenzoic acid is widely used in chemical and biological sectors. This organic compound is used in the treatment of fibrotic skin disorders like Peyronie's disease. It is also employed as an intermediate in the synthesis of folate (Vitamin BX), azo dyes and cross linking agents. PABA is widely useful in the biomedical sector for the preparation of local anaesthetic and ointments. It is widely used in industries to make pharmaceutical products, flavours and preservatives. It is actively involved as a UV-blocking ingredient in sun tan cosmetics.
