| Hazard Information | Back Directory | [General Description]
White crystalline powder. | [Reactivity Profile]
Acidic organic/inorganic salts, such as BENZIDINE DIHYDROCHLORIDE(531-85-1), 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. | [Air & Water Reactions]
This chemical may be sensitive to prolonged exposure to light and air. Slightly soluble in water. | [Fire Hazard]
Flash point data for this chemical are not available; however, BENZIDINE DIHYDROCHLORIDE is probably combustible. | [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.] |
