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 for industrial coloring applications.

Its hydroxyethyl functional group enables reactive bonding to substrates, making it relevant to surface modification processes across several manufacturing sectors. In textile dyeing, it functions as a precursor or coupling component.

It is used in the synthesis of azo dyes applied to fiber substrates, contributing to depth of shade and wash fastness. Leather finishing operations use nitroaniline-based colorants of this type to achieve uniform surface coloration.

In the printing and packaging industry, it supports the formulation of specialty inks where reactive dye chemistry is required for adhesion to coated or treated surfaces. This ensures high-quality results on various materials.

Paper manufacturers incorporate such intermediates into surface treatment processes to achieve tinted or colored paper grades with consistent tone. This chemical is essential for maintaining color uniformity in large-scale production.

Hydroxyethyl-2-nitro-p-toluidine is typically supplied as a solid powder or crystalline material. It is available primarily in technical grade, suited for industrial dye synthesis and colorant manufacturing processes.

Packaging is commonly offered in kilogram-scale quantities for laboratory and pilot use, with bulk options available for production-scale procurement. This flexibility supports both research and industrial applications.
