Description

Pentasodium Bis[5-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-4-Hydroxy-3-[(2-Hydroxy-5-Nitrophenyl)Azo]Naphthalene-2,7-Disulphonato(4-)]Chromate(5-) is a complex chromium-based azo dye intermediate, valued for its role in synthesizing high-performance, colorfast pigments and dyes. This compound matters to manufacturers seeking to produce vibrant, durable colors with excellent light and wash fastness properties for demanding applications. It is primarily needed by the textile, leather, and specialty ink industries for creating high-quality, metal-complex dyes.

Application

• Textile Dyeing: A key intermediate for producing metal-complex dyes used in dyeing wool, nylon, and silk, offering excellent wash and light fastness.
• Leather Finishing: Used in the formulation of dyes for leather goods, providing rich, stable coloration that withstands processing and use.
• Specialty Inks: Employed in the synthesis of pigments for high-performance inks, including those for security printing and specialty coatings.
• Industrial Pigments: Serves as a precursor for manufacturing complex inorganic colorants used in plastics and coatings.
• Research & Development: Utilized in chemical research for developing new chromogenic systems and studying metal-ligand interactions in dye chemistry.

Quality Control

Our Pentasodium Bis[5-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-4-Hydroxy-3-[(2-Hydroxy-5-Nitrophenyl)Azo]Naphthalene-2,7-Disulphonato(4-)]Chromate(5-) undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards for dye intermediates. Production is monitored against strict in-process specifications for critical parameters such as chromophore content and impurity profiles. Certificates of Analysis (COA) detailing purity, identity, and other key metrics 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, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
