N-Ethyl-N-(2-Hydroxyethyl)-4-Nitrosoaniline

Product Overview

N-Ethyl-N-(2-Hydroxyethyl)-4-Nitrosoaniline (CAS 135-72-8) is a high-performance specialty chemical intermediate characterized by its unique push-pull electron structure. Manufactured using an advanced crystallization process, this product is supplied as a stable deep green crystalline powder rather than the standard oily liquid, ensuring superior handling and dosing accuracy in industrial formulations. With an assay purity of ≥98.0%, it serves as a critical building block for diverse high-tech applications ranging from textile dyes to semiconductor materials.

Technical Specifications

Key Applications

• Specialty Azo Dyes And Polymeric Pigments: Acts as a high-reactivity precursor for synthesizing premium azo dyes used in textiles, inkjet printing inks, thermal transfer ribbons, and LCD color filters.
• Cosmetics And Hair Color Developers: Functions as a primary oxidation dye intermediate in permanent and semi-permanent hair coloring formulations, enabling in-situ polymerization for excellent colorfastness.
• Photochemical Sensitizers: Utilized in UV-curing coatings and high-precision photoresists for semiconductor etching due to strong visible and near-UV light absorption.
• Pharmaceutical Synthesis: Serves as a vital building block for constructing complex heterocyclic compounds such as piperazine, indole, and thiophene derivatives in API development.

Storage And Handling

This compound contains a thermally sensitive nitroso group and must be stored in a cool, well-ventilated area away from direct light and heat sources. Handling should occur within a fume hood with appropriate personal protective equipment (PPE) to prevent skin, eye, or respiratory exposure. Proper safety data sheet (SDS) protocols must be followed during transport and usage.
