Description

2-Amino-5-[[2-[[4-[(5-Chloro-2,6-Difluoro-4-Pyrimidinyl)Amino]-2-Sulphophenyl]Azo]-3-Oxobutyroyl]Amino]Benzene-1,3-Disulphonic Acid, Sodium Salt is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its complex molecular structure, featuring a pyrimidine ring, azo linkages, and multiple sulphonic acid groups, makes it a critical precursor for synthesizing advanced colorants with excellent wash-fastness and light-fastness properties. This compound is essential for manufacturers in the textile and specialty chemical industries seeking to produce high-performance dyes and pigments.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the synthesis of high-grade reactive dyes, particularly for cellulose fibers like cotton, viscose, and linen.
• Textile Colorant Production: Used to manufacture dyes that form covalent bonds with fabric, resulting in superior color fastness to washing, light, and perspiration.
• Specialty Pigment Synthesis: Employed in the production of complex organic pigments for inks, coatings, and plastics where high stability is required.
• Research & Development: Utilized in chemical R&D laboratories for developing novel chromophores and studying azo dye chemistry and photostability.
• Fine Chemical Manufacturing: Acts as a sophisticated intermediate in the multi-step synthesis of other specialty chemicals and functional materials.

Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and purity for optimal downstream performance. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
