Description

Disodium 4-[[5-(Aminocarbonyl)-1-Ethyl-1,6-Dihydro-2-Hydroxy-4-Methyl-6-Oxo-3-Pyridyl]Azo]-6-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]Benzene-1,3-Disulphonate is a high-purity, reactive dye intermediate of significant commercial importance. Its core value lies in its bifunctional molecular structure, which enables the creation of highly wash-fast and light-fast colors in textile applications. This compound is essential for manufacturers in the textile and specialty chemical industries seeking to produce advanced, durable dyes and pigments.

Application

• Primary intermediate for reactive dyes used in the dyeing of cotton, viscose, and other cellulosic fibers.
• Key component in the synthesis of high-performance azo-based pigments for industrial coatings and inks.
• Used in research and development for creating novel chromophoric systems with specific light absorption properties.
• Employed in the production of dyes for leather finishing and other specialty applications requiring color fastness.
• Serves as a chemical building block for advanced materials science, including functional polymers.

Quality Control

Our production of Disodium 4-[[5-(Aminocarbonyl)-1-Ethyl-1,6-Dihydro-2-Hydroxy-4-Methyl-6-Oxo-3-Pyridyl]Azo]-6-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]Benzene-1,3-Disulphonate adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance as a dye intermediate. Certificates of Analysis (COA) detailing all 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 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.
