Description

Sodium 4-Chloro-3-[4-[[3-[[(2-Ethylphenyl)Amino]Sulphonyl]-p-Tolyl]Azo]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate is a high-purity, water-soluble azo dye intermediate characterized by its complex molecular structure. This compound is essential for producing vivid and stable colorants, particularly in applications requiring high lightfastness and chemical resistance. It is a critical raw material for manufacturers in the textile, ink, and specialty coatings industries seeking to develop advanced color formulations.

Application

• Primary Intermediate for Reactive Dyes: Synthesis of high-performance reactive dyes for cotton, wool, and nylon fibers.
• Pigment Manufacturing: Used in the production of organic pigments for industrial paints, inks, and plastics.
• Textile Printing: Key component in formulations for textile printing inks, offering excellent wash and rub fastness.
• Leather Dyeing: Employed in dyeing processes for leather goods to achieve deep, uniform colors.
• Paper Coloring: Suitable for specialty paper coloring where high color strength is required.
• Research & Development: Serves as a standard or building block in chemical research for novel chromophore development.

Quality Control

Our production of Sodium 4-Chloro-3-[4-[[3-[[(2-Ethylphenyl)Amino]Sulphonyl]-p-Tolyl]Azo]-4,5-Dihydro-3-Methyl-5-Oxo-1H-Pyrazol-1-Yl]Benzenesulphonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) detailing purity, impurity profile, and physical specifications are provided with each shipment.

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 opening to prevent moisture absorption and degradation. Keep away from incompatible materials.
