Description

5-[[4-[bis[2-[(2-chloroethyl)sulphonyl]ethyl]amino]-6-chloro-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[(2-sulphophenyl)azo]naphthalene-2,7-disulphonic acid, potassium sodium salt is a high-purity, reactive dye intermediate of significant industrial importance. Its complex molecular structure, featuring a triazine core and multiple sulphonic acid groups, provides excellent reactivity and water solubility for creating stable colorants. This compound is essential for manufacturers requiring precise and reliable intermediates to produce specialized dyes and pigments for demanding applications.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-performance fiber-reactive dyes, particularly for cotton and other cellulosic fibers.
• Textile Industry: Used in the production of dyes that offer superior wash-fastness, light-fastness, and brilliant shades.
• Specialty Pigments: Serves as a precursor for creating complex, sulfonated azo pigments with enhanced dispersion properties.
• Research & Development: Employed in chemical R&D for developing novel chromophores and studying dye-polymer interactions.
• Functional Colorants: Potential use in the synthesis of dyes for non-textile applications such as inks or specialty coatings.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality control protocols to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical methods including HPLC for purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation and clumping. Recommended storage temperature is 15-25°C.
