Description

Trisodium 4-[[4-chloro-6-[(2-methyl-4-sulphonatophenyl)amino]-1,3,5-triazin-2-yl]amino]-2-[[1-(2,5-dichloro-4-sulphonatophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl]azo]benzenesulphonate is a high-purity, water-soluble reactive dye intermediate of significant industrial importance. Its complex molecular structure, featuring triazine and pyrazolone moieties, provides excellent chromophoric properties and binding affinity for substrates. This compound is essential for manufacturers requiring consistent, high-performance colorants and specialty chemicals. It serves as a critical building block in the synthesis of advanced dyes and pigments for the textile, ink, and specialty coatings industries.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes used in textile dyeing and printing, particularly for cotton and cellulose fibers.
• Manufacture of specialized pigments and colorants for inks, including those for digital and industrial printing applications.
• Production of colorants for paper coatings and specialty papers requiring vibrant, lightfast colors.
• Key component in the development of functional dyes for non-textile applications, such as in optical media and sensors.
• Used in research and development for creating novel azo-based compounds with specific chemical and physical properties.
• Potential use in the formulation of leather dyes and other industrial coloring processes.

Quality Control

Our trisodium 4-[[4-chloro-6-[(2-methyl-4-sulphonatophenyl)amino]-1,3,5-triazin-2-yl]amino]-2-[[1-(2,5-dichloro-4-sulphonatophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl]azo]benzenesulphonate is manufactured under a strict quality management system to ensure batch-to-batch consistency and purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet exacting industry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with each shipment to guarantee compliance with your technical requirements.

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 absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials.
