Description

2,2'-[[3-Chloro-4-[[4-[[2-(Sulphooxy)Ethyl]Sulphonyl]Phenyl]Azo]Phenyl]Imino]Bisethyl Bis(Hydrogensulphate) is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. This compound is engineered to provide exceptional color strength and covalent bonding properties in advanced textile dyeing and printing applications. It is a critical raw material for manufacturers of high-performance dyes targeting the nylon, wool, and silk sectors, where wash-fastness and brilliance are paramount.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes and acid dyes.
• Key component in manufacturing dyes for textile fibers including nylon, wool, silk, and leather.
• Used in the production of specialized dyes for inkjet printing inks, particularly for technical textiles.
• Employed in research and development of novel chromophoric systems and functional colorants.
• Potential use in the formulation of biological stains and histological dyes for laboratory applications.
• Serves as a precursor for dyes used in the paper coloring industry.

Quality Control

Our production of this dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including HPLC, FT-IR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and stored under conditions of low humidity. Keep away from strong acids and organic solvents.
