Description and Uses

This azoic coloring can be reduced in paraphenylenediamine (PPD). It ean be found in some semipermanent hair dyes, and patch tests are frequently positive (about 30%) in hairdressers with hand dermatitis. Because of cross-sensitivity, the detection of sensitization to p-aminoazobenzene may be assumed by a PPD test.

as a dye for lacquer, varnish, wax products, oi! stains and styrene res ins; in insecticides; used as an intermediate in the manufacture of Acid Yellow, diazo dyes and indulines.
