Description
Application
4-Aminobenzoic acid (4-ABA) can be used in the synthesis of Schiff bases based on 4-ABA with good antibacterial activity. Co(II) and Mn(II) salts of 4-ABA supported on silica gel which in turn can be used as catalysts in oxidation of thiols to disulfides. 4-amino-3-bromobenzoic acid. Curing agent N-(4-carboxyphenyl)trimellitimide (NCPT).
Purpose
For R&D use onlynot for drug household or other uses.
General Description
4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the number 4 carbon in the benzene ring is also known as the para position) is an organic compound with the formula H2NC6H4CO2H. PABA a white-grey crystalline substance is only slightly soluble in water. It consists of a benzene ring substituted with an amino group and a carboxyl group.
