[ USES & STORAGE ] :
 p-Aminobenzoic acid is a part of the folic acid molecule. It was called Vitamin BX as it is a component of pteroylglutamate. But It is considered it does not contribute to synthesize folate in human body. Vitmin BX does not exist as PABA.  In industrial field, it is a starting material in the manufacture of target esters, , salts, folic acid, azo dyes and other organic compounds. It is used as an UV-blocking ingredient in sun tan cosmetics. It is used in medical field for preparing local anesthetic and ointments.  There are three structural isomers. amino group substituted benzoic acid at relative to the hydroxyl group, ortho-, meta-, and para-Aminobenzoic acid. The names of the three compounds indicate which of the hydrogens on the benzene ring portion of the molecule have been replaced. Aminobenzoic acids their derivatives are important for the preparation of other pharmaceutical products, dyes, flavours, and preservatives.
