Description

Disodium 2,5-dichloro-4-[4-[[3-[[4-chloro-6-(2-ethoxyethoxy)-1,3,5-triazin-2-yl]amino]-6-sulphonatophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulphonate is a high-purity, water-soluble reactive dye intermediate essential for modern textile manufacturing. This compound is valued for its ability to form strong covalent bonds with cellulose fibers, resulting in vibrant, wash-fast colors. It is a critical component for industrial producers of reactive dyes targeting the cotton, viscose, and linen markets, where color consistency and fastness are paramount.

Application

• Primary intermediate for the synthesis of high-performance reactive dyes for cellulosic fibers.
• Used in the production of dyes for textile printing and dyeing of cotton, linen, and rayon.
• Key component in manufacturing dyes for exhaust and continuous dyeing processes.
• Enables the creation of dyes with excellent wash, light, and perspiration fastness properties.
• Employed in research and development for novel colorant molecules with enhanced environmental profiles.
• Serves as a standard or reference material for quality control in dye manufacturing.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the exacting standards required for consistent dye synthesis. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and performance reliability for our B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
