p-Phenylenediamine dihydrochloride Chemical Properties,Usage,Production

Chemical Properties
Off-white crystal powder
Usage
Dihydrochloride salt of 1,4-Phenylenediamine (P319845). A hair dye component, paraphenylenediamine, as a contact allergen for treatment of inflammatory diseases.
General Description
White to slightly reddish crystals or gray powder.
Air & Water Reactions
Water soluble.
Reactivity Profile
Acidic organic/inorganic salts, such as p-Phenylenediamine 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 p-Phenylenediamine dihydrochloride are not available; however, p-Phenylenediamine dihydrochloride is probably combustible.
