| benzidine |
a colorless, crystalline arylamine compound formed by the action of acids on hydrazobenzene; once widely used in testing for occult blood, its use is now limited because it is a carcinogen and is toxic if absorbed through the skin, ingested, or inhaled. Called also p-diaminodiphenyl.

(for occult blood in urine or feces): benzidine, acetic acid, and hydrogen peroxide are added to the specimen; hemoglobin catalyzes the oxidation of benzidine by hydrogen peroxide, giving a blue color. This is the most sensitive screening test for occult blood, but it is seldom used because benzidine is a carcinogen, and its use is restricted.
