| benzidine | NH2C6H4C6 H4NH2; p-Diaminodiphenyl;a colourless, crystalline compound used to detect sulfates in water analysis, for the identification of blood, and as a reagent in special stains; because it has been identified as a carcinogen, its current use is limited. (05 Mar 2000) |

| benzidine t. |
(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.
