Description

7-[4-[4-Chloro-6-[4-[2-(Sodiooxysulfonyloxy)Ethylsulfonyl]Anilino]-1,3,5-Triazine-2-Ylamino]-2-Ureidophenylazo]-1,3,6-Naphthalenetrisulfonic Acid Trisodium Salt is a high-purity, reactive dye intermediate and chemical building block of significant commercial importance. Its complex molecular structure, featuring a chlorotriazine core, azo linkage, and multiple sulfonic acid groups, makes it a key precursor for synthesizing high-performance dyes and pigments. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce vibrant, wash-fast colors and advanced functional materials.

Application

• Primary intermediate for reactive dyes used in cotton, wool, and nylon textile dyeing and printing.
• Key building block in the synthesis of high-value azo pigments for inks, coatings, and plastics.
• Used in research and development of functional dyes for optical applications and sensors.
• Employed in the production of colorants for specialty papers and security printing.
• Acts as a chemical anchor or modifier in the synthesis of dye-polymer conjugates for advanced materials.
• Potential use as a starting material for biological staining agents in diagnostic applications.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management systems. Every batch is characterized and tested to ensure consistent chemical structure, purity, and reactivity. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as assay, impurity profile, and functional group content. We support our global clients with documentation to aid their own regulatory and quality assurance processes.

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 after opening to prevent moisture absorption, which can affect reactivity and stability. Keep away from incompatible materials.
