Description

Disodium 4-[[3-[[1-(2-chloro-5-sulphonatophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl]azo]benzoyl]amino]-4'-[(2,5,6-trichloropyrimidin-4-yl)amino][1,1'-biphenyl]-3-sulphonate is a high-purity, reactive dye intermediate of significant commercial importance. This compound is valued for its role in synthesizing high-performance dyes and pigments, particularly for demanding applications requiring excellent color fastness and stability. It is primarily utilized by manufacturers in the textile, ink, and specialty coatings industries seeking to produce vivid and durable colors.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-grade reactive dyes used in textile dyeing and printing, especially for cotton and other cellulosic fibers.
• Pigment Manufacturing: Used in the production of high-performance organic pigments for industrial inks, plastics, and coatings.
• Specialty Colorants: Serves as a precursor for creating specialty dyes used in leather finishing, paper coloring, and other niche applications.
• Research & Development: Employed in chemical R&D for developing new chromophores and studying azo dye chemistry and properties.
• Functional Dyes: Potential use in the synthesis of dyes for non-textile applications, such as in optical data storage or as biological stains.

A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to guarantee consistency and performance for your synthesis processes.

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 each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
