Description

Sodium 2-[[[2-Chloro-4-[[1-(3-Chlorophenyl)-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-4-Yl]Azo]-5-Hydroxyphenyl]Sulphonyl]Amino]Benzoate is a high-purity, synthetic azo dye intermediate with a complex, functionalized molecular structure. This compound is valued for its role as a key precursor in the production of specialized, high-performance pigments and dyes. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries seeking to develop products with specific color fastness and stability properties.

Application

This advanced chemical intermediate serves critical functions in colorant manufacturing and related fields:

• Primary precursor for high-performance azo pigments and dyes used in automotive and industrial coatings.
• Key intermediate in the synthesis of reactive dyes for textile fibers, particularly cotton and nylon, requiring excellent wash and light fastness.
• Manufacturing component for specialty inks, including those for security printing and high-quality packaging.
• Used in research and development for creating novel colorants with tailored chemical and physical properties.
• Potential intermediate in the production of functional dyes for non-textile applications such as lasers or optical media.

Quality Control

Our production of this specialty intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and purity. The material is manufactured under a quality system compliant with ISO 9001 standards. Every lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles, available upon request. We are committed to meeting the precise specifications required for high-end pigment and dye synthesis.

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.
