Description

2-Naphthalenesulfonic acid, 7,7-(2-methyl-1,5-pentanediyl)bisimino(6-fluoro-1,3,5-triazine-4,2-diyl)iminobis4-hydroxy-3-(4-methoxy-2-sulfophenyl)azo-, potassium sodium salt is a high-purity, complex azo dye intermediate with a specific reactive and chromophoric structure. This compound matters for its ability to impart exceptional color fastness, brightness, and chemical stability when incorporated into advanced polymeric materials. It is primarily needed by manufacturers in the synthetic fibers, specialty inks, and high-performance plastics industries seeking to develop products with superior and durable coloration.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-grade reactive dyes used in textile coloring, particularly for cotton and polyamide fibers.
• Polymer & Resin Coloring: Imparts stable, vibrant color to engineering plastics, synthetic fibers (like nylon and polyester), and specialty resins.
• Inkjet & Digital Printing Inks: Used in the formulation of high-performance inks requiring excellent lightfastness and water resistance.
• Optical Applications: Potential use in filters, lenses, or other optical components where specific light-absorption properties are required.
• Research & Development: Serves as a sophisticated building block in chemical research for developing new chromophores and functional materials.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Every lot undergoes comprehensive analysis, including HPLC for purity, spectrophotometry for color strength, and elemental analysis. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance and regulatory needs.

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 nature, the container must be kept sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
