Description

Trisodium n-[2-[[2-[4-[[1-Amino-8-Hydroxy-7-(Phenylazo)-3,6-Disulphonato-2-Naphthyl]Azo]Phenyl]-1H-Benzimidazol-5-Yl]Azo]-5-Hydroxyphenyl]Glycinate is a high-purity, water-soluble azo dye intermediate of significant industrial importance. Its complex poly-azo structure, featuring multiple sulfonate groups, provides excellent substantivity and chromophore properties for creating deep, vibrant colors. This compound is essential for manufacturers requiring precise and reliable intermediates to produce specialized dyes and pigments for demanding applications.

Application

• Textile Dyeing: A key intermediate for synthesizing high-performance acid dyes and reactive dyes used on nylon, wool, silk, and other protein fibers.
• Leather Coloring: Used in the production of dyes for imparting deep, uniform shades to leather goods with good fastness properties.
• Ink Manufacturing: Serves as a precursor for pigments and dyes in specialty inks, including those for packaging and security printing.
• Paper Coloring: Employed in the synthesis of dyes for high-quality paper products where color consistency is critical.
• Research & Development: Used as a standard or building block in chemical research for developing novel chromophores and functional dyes.
• Specialty Pigments: Acts as an intermediate for creating complex organic pigments with specific hue and stability requirements.

Quality Control

Our production of Trisodium n-[2-[[2-[4-[[1-Amino-8-Hydroxy-7-(Phenylazo)-3,6-Disulphonato-2-Naphthyl]Azo]Phenyl]-1H-Benzimidazol-5-Yl]Azo]-5-Hydroxyphenyl]Glycinate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot undergoes rigorous analytical testing, including chromatographic purity analysis and spectrophotometric identification. 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 at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
