Description

Trisodium 3-[[4-[[4-Chloro-6-[Phenyl(Sulphonatomethyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Methoxy-o-Tolyl]Azo]Naphthalene-1,5-Disulphonate is a high-purity, water-soluble anionic dye belonging to the class of reactive and direct azo dyes, distinguished by its triazine and naphthalene disulfonate structure. This compound is engineered to deliver exceptional color strength, lightfastness, and wash fastness, making it a critical component for demanding coloration processes. It is primarily required by manufacturers in the textile, paper, and specialty ink industries seeking reliable and consistent dye performance for high-value products.

Application

• Textile Dyeing: A key dye for cotton, viscose, and other cellulosic fibers, offering excellent substantivity and fixation.
• Paper Coloring: Used in the production of high-quality colored papers, including specialty packaging and decorative papers.
• Ink Formulation: Employed in the manufacture of inks for flexographic, inkjet, and other printing applications requiring vivid shades.
• Leather Finishing: Applied in dyeing leather goods to achieve deep, uniform colors with good durability.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its specific affinity.
• Chemical Intermediate: Serves as a synthetic intermediate for producing more complex dye molecules and pigments.

Quality Control

Our production of Trisodium 3-[[4-[[4-Chloro-6-[Phenyl(Sulphonatomethyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Methoxy-o-Tolyl]Azo]Naphthalene-1,5-Disulphonate adheres to a rigorous quality management system. Every batch is analyzed to ensure it meets strict specifications for dye content, shade, strength, and impurity profiles. Certificates of Analysis (COA) documenting key parameters such as purity, solubility, and heavy metal content are provided to guarantee batch-to-batch consistency and compliance with industry standards.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance and flow characteristics.
