Description

Hexasodium 4,4'-[1,4-Phenylenebis[Imino(6-Chloro-1,3,5-Triazine-4,2-Diyl)Imino]]Bis[5-Hydroxy-6-[(2-Sulphonatophenyl)Azo]Naphthalene-2,7-Disulphonate] is a high-performance, water-soluble reactive dye intermediate, specifically engineered for the synthesis of brilliant and wash-fast dyes. Its complex polyfunctional structure, featuring multiple reactive chlorotriazine groups and sulphonate moieties, is critical for achieving superior covalent bonding to cellulosic fibers like cotton and viscose. This compound is an essential raw material for industrial manufacturers seeking to produce reactive dyes with excellent color yield, high fixation rates, and outstanding wet fastness properties.

Application

This advanced chemical intermediate is primarily utilized in the synthesis of high-grade reactive dyes for the textile industry. Its specific applications include:

• Primary Intermediate for Reactive Dyes: Serving as the core chromophore and reactive component in the manufacture of polyfunctional reactive dyes for cellulose fibers.
• Textile Dyeing and Printing: Used in the production of dyes for exhaust, pad-batch, and continuous dyeing processes, as well as for textile printing inks.
• High-Washfastness Dye Formulations: Ideal for creating dyes where exceptional resistance to washing, perspiration, and chlorine is required, such as in home textiles and high-performance apparel.
• Bright Shade Development: Key for formulating brilliant red, violet, and blue shades with high tinctorial strength.
• Industrial Colorants: Potential use in the synthesis of specialized colorants for paper, leather, and other substrates requiring reactive dye chemistry.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and purity. Every lot is analyzed using advanced techniques like HPLC and spectrophotometry to confirm chemical identity, reactive group content, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, strength, and critical physical parameters is provided with each 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 after opening to prevent moisture absorption, which can affect reactivity and handling properties.
