Description

2,2'-[1,4-Phenylenebis[Imino(6-Chloro-1,3,5-Triazine-4,2-Diyl)Imino(8-Hydroxy-3,6-Disulphonaphthalene-1,7-Diyl)Azo]]Bisnaphthalene-1,5-Disulphonic Acid is a high-purity, complex organic dye intermediate characterized by its polyfunctional structure containing triazine, azo, and multiple sulphonic acid groups. This compound is valued for its ability to impart excellent lightfastness, wash fastness, and vibrant color properties when incorporated into advanced dye systems. It is primarily sought after by manufacturers in the textile, specialty ink, and high-performance pigment industries for producing durable and vivid colorants.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-grade reactive dyes for cotton, wool, and polyamide fibers, offering superior bonding and color yield.
• Textile Colorants: Used in the production of dyes that provide excellent fastness to light, washing, and perspiration for the textile industry.
• Specialty Inks: Serves as a precursor for pigments and dyes used in high-performance inks for packaging, security printing, and digital textiles.
• Functional Dyes: Potential applications in the synthesis of dyes for non-textile uses, such as in optical data storage, liquid crystal displays (LCDs), or laser dyes.
• Research & Development: Employed as a standard or building block in chemical research for developing novel chromophores and functional materials.

Quality Control

Our production of 2,2'-[1,4-Phenylenebis[Imino(6-Chloro-1,3,5-Triazine-4,2-Diyl)Imino(8-Hydroxy-3,6-Disulphonaphthalene-1,7-Diyl)Azo]]Bisnaphthalene-1,5-Disulphonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and quality assurance.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
