Bis(4-aminobenzoic acid-κN)dichloridozinc(II) [PDF]
Acta Crystallographica Section E, 2010 Molecules of the title compound [ZnCl2(C7H7NO2)2], are located on a twofold rotation axis. Two 4-aminobenzoic acid moieties, and two chloride ligands are coordinated to a Zn atom in a tetrahedral fashion, forming an isolated molecule.

Corrosion resistance of stainless steel covered by 4-aminobenzoic acid films [PDF]
Open Chemistry, 2012 Abstract The protective, anticorrosion properties of 4-aminobenzoic acid (4-ABA) films are evaluated in the paper. The 4-ABA films were electrodeposited on the surface of both X20Cr13 stainless steel and glassy carbon electrodes by galvanostatically and cyclic voltammetry methods.

Enzymatic method for selective determination of 4-aminobenzoic acid in urine [PDF]
Clinical Chemistry, 1990 Abstract We developed a method for the selective determination of 4-aminobenzoic acid by use of 4-aminobenzoate hydroxylase (EC 1.14.13.27) to convert 4-aminobenzoic acid to 4-hydroxyaniline. The subsequent conversion of 4-hydroxyaniline to indophenol dye was quantified colorimetrically. The method is reproducible, and the assay response
