Description

Tetrasodium 5-[[4-[[4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-7-Sulphonato-1-Naphthyl]Azo]-2,5-Dimethylphenyl]Azo]Naphthalene-1,3,6-Trisulphonate is a high-purity, water-soluble reactive dye intermediate essential for the synthesis of advanced colorants. This compound is valued for its ability to form covalent bonds with substrates, resulting in dyes with excellent wash-fastness, light-fastness, and brilliant hues. It is a critical raw material for manufacturers in the textile, leather, and specialty ink industries seeking to produce high-performance, durable dyes.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing high-quality reactive dyes used in cellulose fiber (cotton, viscose) dyeing and printing.
• Textile Industry: Enables the production of dyes for textiles requiring superior color fastness to washing, light, and perspiration.
• Leather Coloring: Used in the synthesis of dyes for leather finishing, providing vibrant and durable colors.
• Paper Dyeing: Intermediate for colorants used in specialty paper and packaging applications.
• Ink Formulation: Serves as a precursor for pigments and dyes in inks for digital textile printing and other specialty applications.
• Research & Development: Used in chemical R&D for developing novel chromophores and studying dye-substrate interactions.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques like HPLC and spectrophotometry to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with every shipment to support your quality assurance protocols.

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, which can affect product stability and performance.
