N-METHYL-O-PHENYLENEDIAMINE DIHYDROCHLORIDE(25148-68-9) is an acidic salt. Materials in this group are generally soluble in water. The resulting solutions contain moderate 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.

Water soluble.

N-Methyl-o-phenylenediamine, Dihydrochloride (cas# 25148-68-9) is a compound useful in organic synthesis.

In a dry reaction flask, N-methylphthalimide was dissolved in methanol and then dilute aqueous hydrochloric acid was slowly added to the reaction flask and the resulting reaction mixture was stirred at room temperature for several hours. Directly after th
