Benzidine dihydrochloride Chemical Properties,Uses,Production
Uses
The dihydrochlorie salt of Benzidine (B121000) a common used in dyes and environmental testing.
General Description
White crystalline powder.
Air & Water Reactions
Benzidine dihydrochloride may be sensitive to prolonged exposure to light and air. Slightly soluble in water.
Reactivity Profile
Acidic organic/inorganic salts, such as Benzidine dihydrochloride, are generally soluble in water. The resulting solutions contain moderate to high concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Fire Hazard
Flash point data for Benzidine dihydrochloride are not available; however, Benzidine dihydrochloride is probably combustible.
Biological Activity
Tumor initiator in mammary glands of experimental animal.
Safety Profile
Suspected carcinogen with experimental carcinogenic and tumorigenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of HCl and NOx.
Purification Methods
Benzidine dihydrochloride [531-85-1] M 257.2, m >250o(dec). Crystallise the salt by dissolving in hot H2O, and adding conc HCl to the slightly cooled solution. CARCINOGENIC.[Beilstein 13 IV 365.]
