Chemical Properties

Redish Powder

Uses

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

General Description

Crystals (from ethanol); light purple powder.

Air & Water Reactions

Water soluble.

Reactivity Profile

N-Methyl-1,2-benzenediamine dihydrochloride 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.

Fire Hazard

Flash point data for N-Methyl-1,2-benzenediamine dihydrochloride are not available; however, N-Methyl-1,2-benzenediamine dihydrochloride is probably combustible.
