Description

Trisodium 5-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-4-Hydroxy-3-[(2-Sulphonatophenyl)Azo]Naphthalene-2,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant industrial importance. This compound is valued for its ability to form covalent bonds with substrates, offering excellent wash and light fastness properties in the final colored product. It is primarily required by manufacturers in the textile, leather, and specialty chemical industries for producing vibrant and durable dyes and pigments.

Application

• Primary Intermediate for Reactive Dyes: Key starting material for synthesizing high-performance reactive dyes used in cellulose fiber (cotton, rayon) dyeing and printing.
• Leather Coloring Agent: Used in the formulation of dyes for leather finishing, providing deep, stable colors.
• Paper Dye Manufacture: Employed in the production of dyes for specialty paper and paperboard coloring.
• Inkjet Ink Formulations: Serves as a colorant precursor in the manufacture of certain industrial inkjet inks.
• Research & Development: Used in chemical R&D for developing new chromophores and studying azo-triazine chemistry.
• Specialty Chemical Synthesis: Intermediate for creating other functional chemicals where a sulfonated azo-triazine structure is required.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay, impurity profile, and physical specifications is provided with each shipment to support your quality assurance processes.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
