Use of m-phenylenediamine

[Purpose 1]

It is used as analytical reagent, resin curing agent and polymerization inhibitor, and also for the synthesis of dyes

[Purpose 2]

Mainly used as dye intermediate and curing agent of epoxy resin

[purpose 3]

The intermediates of azo dyes and acridine dyes are mainly used to manufacture dyes such as direct sun fastness and black RN, basic orange, basic Brown g, direct sun fastness and black G, and used as fur dyes. In Japan, the consumption of m-phenylenediamine for azo dyes accounts for 90% of the total consumption. It can also be used as curing agent of epoxy resin, coagulant of cement, hair dye, mordant, developer, etc.

[Purpose 4]

Determination of nitrite by spectrophotometry, bromate, bromide, chromate, ozone, gold, copper, dichromate, iron, oxygen and platinum, active chlorine, chromium, iridium, nitrite and palladium.
