P-Phenylenediamine CAS# 106-50-3

P-phenylenediamine (PPD) is an organic compound with the molecular formula C 6H 4 (NH 2) 2. This aniline derivative is a white strong, however the sample will darken because of air oxidation. It is mainly utilized as engineering polymer and also Kevlar composite materials. It is additionally an active ingredient in hair dyes as well as is periodically utilized as a substitute for henna.

P-phenylenediamine is among the simplest fragrant diamines. The pure product is white to purplish red crystal. It turns purple or dark brown when revealed to air. A little soluble in cold water, soluble in ethanol, ether, chloroform and also benzene. It can be utilized to produce azo dyes, high molecular polymers, hair dyes, rubber anti-oxidant and designer, generally utilized for Kevlar, azo dyes, sulfur dyes, acid dyes, and so on. It is made use of to create black hair D, black fur dB, brown fur N2 as well as rubber antioxidant DNP, DOP and megabytes. It can likewise be utilized as basic material for cosmetics and also hair p-phenylenediamine series, fuel polymerization prevention and also designer.
