Applications of 99-56-9

The primary application of 4-nitro-o-phenylenediamine is in the cosmetic industry as a component of oxidation hair dyes. It is used at concentrations typically not exceeding 1% in formulations, which translates to about 0.5% upon application after mixing with hydrogen peroxide. Beyond cosmetics, its mutagenic properties have made it a subject of study in toxicology and environmental science.
