Description

Tetrasodium 5-Benzamido-3-(5-(4-Fluoro-6-(1-Sulphonato-2-Naphthylamino)-1,3,5-Triazin-2-Ylamino)-2-Sulphonatophenylazo)-4-Hydroxynaphthalene-2,7- Disulphonate is a high-performance, water-soluble anionic dye belonging to the reactive dye class, known for its complex polyazo structure. This compound is engineered to deliver exceptional color fastness, brightness, and wash resistance on cellulosic fibers like cotton and viscose. It is a critical component for industrial dye houses and textile manufacturers seeking to produce vibrant, durable, and high-quality colored fabrics.

Application

• Primary Textile Dyeing: Exhaust and continuous dyeing of cotton, linen, and other cellulosic fibers.
• Textile Printing: Used in pigment printing pastes for sharp, bright prints on natural fabrics.
• Leather Coloring: Application in dyeing leather goods where deep, stable coloration is required.
• Paper Industry: Coloring of specialty papers, including decorative and packaging papers.
• Ink Formulation: A key colorant for certain types of industrial inks requiring specific solubility and stability profiles.
• Research & Development: Serves as a reference standard or intermediate in the synthesis of novel dye molecules and colorants.

Quality Control

Our production of Tetrasodium 5-Benzamido-3-(5-(4-Fluoro-6-(1-Sulphonato-2-Naphthylamino)-1,3,5-Triazin-2-Ylamino)-2-Sulphonatophenylazo)-4-Hydroxynaphthalene-2,7- Disulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Every lot undergoes rigorous testing for key parameters including color strength, shade, solubility, and impurity profile. Certificates of Analysis (COA) documenting these results are available upon request 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 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 and handling.
