Description

Hexasodium 4-Amino-3,6-Bis[[4-[[4-Chloro-6-[(3-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-2-Sulphonatophenyl]Azo]-5-Hydroxynaphthalene-2,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant industrial importance. Its complex polyazo structure, featuring multiple sulphonate groups and reactive chlorotriazine moieties, makes it a critical precursor for synthesizing high-performance dyes. This compound is essential for manufacturers requiring consistent quality and reliable supply for advanced coloration processes. It is primarily utilized in the production of reactive dyes for textiles, leather, and paper.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing high-washfastness and lightfastness reactive dyes used in cotton, viscose, and other cellulosic fiber dyeing.
• Textile Industry: Used in the synthesis of polyfunctional dyes for exhaust, pad-batch, and continuous dyeing processes, offering excellent color yield and fixation.
• Leather Coloring: Serves as a precursor for dyes applied in the leather tanning and finishing industry.
• Paper Dyeing: Employed in the production of dyes for specialty paper and packaging materials.
• Ink Formulations: Can be used in the development of specialized inks where water solubility and color intensity are required.
• Research & Development: Serves as a standard or starting material in chemical R&D for novel dye structures and applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling. Keep away from incompatible materials.
