Description

Hexasodium 4-Amino-3,6-Bis[[4-[[4-Chloro-6-[(4-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-2-Sulphonatophenyl]Azo]-5-Hydroxynaphthalene-2,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its complex molecular structure, featuring multiple sulphonate groups and reactive chlorotriazine moieties, makes it a critical precursor for synthesizing high-performance, wash-fast dyes. This compound is essential for manufacturers in the textile and specialty chemical industries seeking to produce brilliant, durable colorants for natural and synthetic fibers.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing high-quality reactive dyes used in cotton, wool, silk, and nylon dyeing and printing.
• Textile Industry: Enables the production of dyes with excellent color yield, wet fastness, and brilliant shades, particularly in red to blue color ranges.
• Specialty Pigments: Used in the synthesis of certain high-value, water-soluble pigments for inks and coatings.
• Research & Development: Serves as a standard or starting material in chemical R&D for developing new chromophores and dye systems.
• Paper Coloring: Potential application in the manufacture of dyes for specialty paper products requiring high color stability.

Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and high chemical purity. Every 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 each shipment to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
