NCIt definition : A grayish-red, yellowish or white colored, very toxic, crystalline aromatic amine
that darkens when exposed to air and light. Benzidine has been widely used for the
detection of blood and as a reagent in the manufacture of dyes. Ingestion of benzidine
causes cyanosis, headache, mental confusion, nausea and vomiting. Its use is now limited
because of strong association between exposure to benzidine and an increased risk
of bladder cancer in humans. (NCI05);
