What is Hydroxyethyl-2-nitro-p-toluidine?
Hydroxyethyl-2-nitro-p-toluidine (CAS 100418-33-5), also known as 4-(2-Hydroxyethylamino)-3-nitrotoluene, is a nitroaniline-derived colorant intermediate used in the production of dyes and pigments.
Where is Hydroxyethyl-2-nitro-p-toluidine used?
- Textile dyeing: precursor or coupling component
- Azo dye synthesis for fiber substrates, contributing depth of shade and wash fastness
- Leather finishing: uniform surface coloration
- Printing and packaging: specialty inks requiring reactive dye chemistry for adhesion to coated or treated surfaces
- Paper manufacturing: surface treatment for tinted or colored paper grades with consistent tone
- Its hydroxyethyl functional group enables reactive bonding to substrates in surface modification.
Commercial specifications
- Packaging: kilogram-scale quantities for laboratory and pilot use; bulk options for production-scale procurement
