GENERAL DESCRIPTION OF BENZIDINE
Benzidine is the trival name for 4,4'-diaminobiphenyl which two hydrogen atoms on biphenyl molecules are replaced by amines at para position each. It is a white to slightly reddish crystalline powder turns dark on exposure to air and light; melting point of 128 C. This compound decomposes on heating and reacts violently with strong oxidants, particularly nitric acid. It is produced by the action of acids on diphenyldrazine. Benzidine can be classified as arylamine which one or more of the hydrogen atoms are replaced by aromatic groups such as homologues of aniline, p-aminobiphenyl, benzidine, and naphthylamine. Some arylamines are carcinogenic and the uses are restricted. Benzidne forms a blue precipitate with hemoglobin. Hemoglobin catalyzes the oxidation of benzidine to a polymer by hydrogen peroxide, which gives the blue color. This was the common screening test for occult blood. But the use is restricted due to cancer suspect. Benzidine is the starting material in the dye manufacturing. Numerous substituted group on the benzidine ring system as well as amine groups offer important roles to each characteristic colours directly and in preparing next target colorants. It is important in azo dyes production due to strong fix to cotton. It and its derivatives have active applications in the synthesis of dyes, pigments, paints, rubber compounding agents and wide range of organic chemicals.  Biphenyl structure of benzidine also provide the application in luminescence chemistry, spectrophotometric analysis, molecular chemistry, and as a stating material for organometallic-complexes. Benzidine molecules are used in dye production industry and certain other industrial fields. Benzidine molecules include:
