Description

2-[[[2-Chloro-4-[[1-(3-Chlorophenyl)-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-4-Yl]Azo]-5-Hydroxyphenyl]Sulphonyl]Amino]Benzoic Acid is a specialized azo dye intermediate known for its complex molecular structure and high-performance characteristics. This compound is valued for its role in synthesizing advanced colorants with excellent fastness properties and specific functional attributes. It is primarily required by manufacturers in the dye and pigment, specialty chemical, and advanced material industries for high-end applications.

Application

• Key intermediate for the synthesis of high-performance azo disperse dyes and pigments.
• Used in the coloration of synthetic fibers, particularly polyester and nylon, where wash and light fastness are critical.
• Potential precursor for functional dyes used in non-linear optics (NLO) and electronic applications.
• Employed in research and development of novel sensitizers for dye-sensitized solar cells (DSSCs).
• Intermediate for specialty colorants used in inks, coatings, and plastics requiring specific chromatic and stability properties.
• Starting material for the development of biological stains and diagnostic reagents in life sciences.

Quality Control

Our production of this advanced intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and mass spectrometry to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with every shipment 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
