Description

Trisodium 4-[(4-Amino-9,10-Dihydro-9,10-Dioxo-3-Sulphonato-1-Anthryl)Amino]-6-[(2,5,6-Trichloropyrimidin-4-Yl)Amino]Benzene-1,3-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its core value lies in its ability to form stable covalent bonds with textile fibers, providing exceptional color fastness and wash resistance. This compound is essential for manufacturers of reactive dyes targeting the textile industry, particularly for dyeing and printing cotton and other cellulosic fibers.

Application

This specialized anthraquinone-pyrimidine based intermediate is a key building block for high-performance reactive dyes. Its primary and related applications include:

• Primary Intermediate for Reactive Dyes: Synthesis of high-quality reactive dyes for the textile industry.
• Cotton Dyeing: Production of dyes used in exhaust and continuous dyeing processes for cotton fabrics.
• Textile Printing: Formulation of printing inks and pastes for textile printing applications.
• Cellulosic Fiber Coloring: Dyeing of other cellulosic fibers like viscose, linen, and hemp.
• High-Washfastness Dyes: Creating dyes that meet stringent standards for household and industrial laundering.
• Research & Development: Used in R&D labs for developing novel dye structures and colorants.
