Definition

ChEBI: A primary amino compound that is p-phenylenediamine in which one of the hydrogens attached to the benzene ring is replaced by a nitro group. It is a cosmetic hair dye intermediate that is used in permanent hair colouring products (diluted 1:1 ith an oxidising agent prior to application).

General Description

Almost black needles with dark-green luster or black powder.

Reactivity Profile

2-NITRO-P-PHENYLENEDIAMINE(5307-14-2) is incompatible with strong oxidizing agents.

Air & Water Reactions

This chemical may be sensitive to prolonged exposure to light and air. Insoluble in water.

Fire Hazard

Flash point data for this chemical are not available; however, 2-NITRO-P-PHENYLENEDIAMINE is probably combustible.

Description

o-Nitro-paraphenylenediamine (ONPD) is a hair dye and a sensitizer in hairdressers.

Uses

2-Nitro-4-phenylene-diamine is a dyestuff used to dye furs brown and reddish-brown; dye intermediate in semi-permanent and permanent hair coloring products (produces brown and red shades on the hair); in different hair-dyeing preparations.

Uses

This compound is used in hair and fur dyes.

Flammability and Explosibility
