Description

Disodium 6-Amino-3-[[4-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]-2-Sulphonatophenyl]Azo]-4-Hydroxynaphthalene-2-Sulphonate is a high-purity, water-soluble azo dye intermediate characterized by its complex, functionalized molecular structure. This compound matters for its role as a critical precursor in the synthesis of specialized reactive and direct dyes, offering excellent color fastness and affinity for cellulosic fibers. It is primarily needed by manufacturers in the textile dyeing and printing industries, as well as by research institutions developing advanced colorants and functional materials.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-performance reactive dyes used on cotton, viscose, and other natural fibers.
• Manufacture of Direct Dyes: Used in the production of direct dyes, valued for their application simplicity and good wash-fastness properties.
• Specialty Colorant Research: Serves as a sophisticated starting material in R&D for novel dyes with specific optical or functional properties.
• Textile Printing Inks: A component in the formulation of inks for digital and conventional textile printing processes.
• Biomolecular Staining: Potential application in the development of histological stains or fluorescent probes due to its azo chromophore and sulphonate groups.
• Analytical Chemistry Reagent: Can be used as a standard or reagent in analytical methods for dye identification and quantification.

Quality Control

Our Disodium 6-Amino-3-[[4-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]-2-Sulphonatophenyl]Azo]-4-Hydroxynaphthalene-2-Sulphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent chemical structure, and batch-to-batch reproducibility, meeting the exacting standards required for dye synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
