Description

Ammonium Sodium Hydrogen -2-[[6-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]-5-Methoxybenzene-1,4-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its core value lies in its role as a key building block for synthesizing high-performance, colorfast dyes and pigments, particularly in the textile industry. This compound is essential for manufacturers and R&D facilities specializing in the production of reactive dyes for cotton, wool, and polyamide fibers, where it contributes to brilliant shades and excellent wash-fastness properties.

Application

• Primary intermediate in the synthesis of reactive dyes for textile printing and dyeing.
• Key component for producing high-value azo dyes with superior color strength and fastness properties.
• Used in the manufacture of dyes for cotton, wool, silk, and nylon fibers.
• Research and development of novel coloration chemicals and specialty pigments.
• Potential intermediate in the synthesis of colorants for inks and specialty coatings.
• Used in analytical chemistry as a reference standard for quality control in dye production.
