N,N'-bis(2-hydroxyethyl)-2-nitro-p-phenylenediamine

N,N'-Bis(2-hydroxyethyl)-2-nitro-p-phenylenediamine (CAS 84041-77-0) is a nitro-based aminophenol dye intermediate used primarily in oxidative and direct hair coloring systems.

Where is N,N'-bis(2-hydroxyethyl)-2-nitro-p-phenylenediamine used?

• Cosmetic formulations: semi-permanent violet and red-violet shades on treated and natural hair fibers
• Hair color products: direct dye
• It deposits color without an oxidative developer and is blended with other nitro dyes for targeted shade ranges.
• Textile dyeing: protein-based fibers such as wool and silk
• Leather finishing: dye baths for surface coloration
• Specialty paper: surface tinting

Good to know: Cosmetic-grade material is the primary commercial specification, with purity aligned to EU and international cosmetic ingredient standards. Technical-grade supply is standard for leather applications.
