Description

Trisodium 6-Amino-5-[[5-[[5-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]-2-Sulphonatophenyl]Amino]-2-Sulphonatophenyl]Azo]Naphthalene-1-Sulphonate is a high-purity, water-soluble reactive dye intermediate characterized by its complex polyazo and heterocyclic structure. This compound matters for its role as a critical precursor in synthesizing high-performance, colorfast reactive dyes, particularly for demanding textile applications. It is primarily needed by manufacturers in the textile dye and pigment industries seeking to produce vibrant, wash-fast colors on cellulosic fibers like cotton.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the synthesis of high-grade reactive dyes for cotton, viscose, and other cellulosic fabrics.
• Textile Coloration: Used in dye formulations requiring excellent wash-fastness, light-fastness, and brilliant shades, especially reds and blues.
• Specialty Pigment Manufacturing: Can be utilized in the production of certain high-performance organic pigments for inks and coatings.
• Research & Development: Employed in chemical R&D for developing novel chromophores and studying azo dye chemistry and photostability.
• Dyeing Process Optimization: Used by technical teams to formulate specific dyeing recipes for achieving consistent and reproducible color results on an industrial scale.

Quality Control

Our Trisodium 6-Amino-5-[[5-[[5-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]-2-Sulphonatophenyl]Amino]-2-Sulphonatophenyl]Azo]Naphthalene-1-Sulphonate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent chemical structure, and batch-to-batch reproducibility, which are critical for reliable dye synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
