Description

7-[[4-Chloro-6-[(3-Sulphophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(4-Methoxy-2-Sulphophenyl)Azo]Naphthalene-2-Sulphonic Acid is a high-purity, complex anionic dye intermediate essential for synthesizing vibrant and wash-fast colorants. This compound matters for its role as a key building block in creating high-performance reactive and direct dyes with excellent substantivity and chroma. Industrial manufacturers in the textile, leather, and specialty ink sectors need this intermediate to produce dyes that meet stringent quality and durability standards for their end products.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes used in cotton and cellulose fiber dyeing.
• Key precursor in the manufacture of direct dyes for paper, leather, and textile applications.
• Used in the production of specialized colorants for inks and toners requiring specific lightfastness and chemical resistance.
• Employed in research and development for creating novel azo-based pigments and functional dyes.
• Serves as a chemical building block for dyes used in biological staining and histological applications.
• Potential use in the synthesis of colorimetric sensors and indicators due to its distinct chromophoric system.

Quality Control

Our production of this dye intermediate adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and high purity. While typically supplied as a technical grade material, specifications can be adjusted to meet specific customer requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee compliance with your manufacturing 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 to prevent moisture absorption. Keep away from strong acids and incompatible organic solvents.
