Description

2-[[4-[[4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-5-Sulpho-1-Naphthyl]Azo]-2,5-Dimethylphenyl]Azo]Benzene-1,4-Disulphonic Acid is a high-purity, complex azo dye intermediate characterized by its multi-sulfonic acid and triazine functional groups. This compound matters for its critical role in synthesizing high-performance, wash-fast, and light-fast reactive dyes and pigments for demanding industrial applications. Manufacturers in the textile, leather, and specialty ink industries need this precise chemical building block to produce vivid, durable colors that meet stringent quality and regulatory standards.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key precursor in the manufacture of high-quality reactive dyes for cotton, wool, and nylon, offering excellent fiber affinity and covalent bonding.
• Specialty Pigment Synthesis: Used in the production of complex organic pigments for automotive paints, industrial coatings, and plastics requiring superior color strength and weatherfastness.
• Leather Dyeing: Employed in formulating dyes for leather processing, providing deep, uniform shades with good penetration and fastness properties.
• Inkjet Ink Formulations: A valuable component in the synthesis of dyes for professional and industrial inkjet inks, particularly where high color gamut and stability are required.
• Research & Development: Used in chemical R&D for developing novel chromophores and studying structure-property relationships in dye chemistry.

Quality Control

Our production of this advanced dye intermediate adheres to rigorous quality control protocols to ensure batch-to-batch consistency and purity. Quality is verified through comprehensive analytical techniques including HPLC, UV-Vis, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment 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 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 stability and performance. Keep away from incompatible materials.
