NCIt definition : A colorless, crystalline compound that emits toxic fumes of nitrogen oxides when heated
to decomposition. Hydrazobenzene has been used primarily in the dye manufacturing
industry as the precursor of the dye intermediate benzidine and is also used as an
intermediate in the manufacture of pharmaceuticals. Exposure to this substance irritates
the skin, nose, throat and lungs and can eventually lead to liver, kidney and brain
damage. Hydrazobenzene is reasonably anticipated to be a human carcinogen based on
evidence of carcinogenicity in experimental animals. (NCI05);
