Description

Sodium 4-Chloro-3-[4-[[2,2'-Dimethyl-4'-[[4-[(Phenylsulphonyl)Oxy]Phenyl]Azo][1,1'-Biphenyl]-4-Yl]Azo]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate is a high-purity, synthetic organic chemical compound primarily used as a specialized dye intermediate. Its complex azo-biphenyl-pyrazole structure provides unique chromophoric properties essential for producing vivid and stable colorants. This product is critical for manufacturers in the textile, ink, and specialty polymer industries seeking to develop advanced, high-performance pigments and dyes with specific lightfastness and solubility characteristics.

Application

• Primary Intermediate for Azo Dyes & Pigments: Serves as a key building block in the synthesis of high-value, complex azo dyes, particularly for textiles and inks requiring specific shades and properties.
• Specialty Ink Formulations: Used in the production of pigments for advanced printing inks, including those for security printing, packaging, and digital applications.
• Functional Polymer Additives: Can be incorporated into polymers to impart color or act as a functional monomer in specialty resin systems.
• Research & Development: Employed in chemical R&D for developing novel chromophores, studying dye-sensitized solar cells (DSSCs), or creating molecular probes.
• Liquid Crystal Dyes: Potential application in the synthesis of dyes for liquid crystal displays (LCDs) due to its planar, conjugated structure.

Quality Control

Our Sodium 4-Chloro-3-[4-[[2,2'-Dimethyl-4'-[[4-[(Phenylsulphonyl)Oxy]Phenyl]Azo][1,1'-Biphenyl]-4-Yl]Azo]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and physical properties are provided and available upon request to support your quality assurance protocols.

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 opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
