Description

4-Methyl-2,6-Bis[[2-(Sulphooxy)Ethyl]Amino]-5-[[4-[[2-(Sulphooxy)Ethyl]Sulphonyl]Phenyl]Azo]Nicotinonitrile, Sodium Salt is a specialized, water-soluble anionic dye intermediate characterized by its multiple sulphooxy and sulphonyl functional groups. This compound is engineered for high-performance applications where strong substantivity, solubility in aqueous systems, and the ability to form covalent bonds or stable complexes are critical. It serves as a key precursor for the synthesis of advanced reactive dyes and colorants, primarily targeting the textile and specialty chemical manufacturing sectors.

Application

• Reactive Dye Synthesis: Primary intermediate for manufacturing high-washfastness reactive dyes for cotton, wool, and polyamide fibers.
• Textile Printing Inks: Used in the formulation of specialized inks for digital and screen printing on natural and synthetic fabrics.
• Functional Colorants: Serves as a building block for creating colorants with specific functional properties for technical applications.
• Research & Development: A valuable chemical entity for R&D in novel chromophore systems and dye-polymer conjugates.
• Specialty Coatings: Potential use in the development of colored coatings where water solubility and ionic character are advantageous.

Quality Control

Every batch of our 4-Methyl-2,6-Bis[[2-(Sulphooxy)Ethyl]Amino]-5-[[4-[[2-(Sulphooxy)Ethyl]Sulphonyl]Phenyl]Azo]Nicotinonitrile, Sodium Salt is produced and tested under a strict quality management system. We ensure compliance with consistent purity and performance standards critical for dye synthesis. Comprehensive analytical testing, including HPLC for assay and impurity profiling, is performed. A detailed Certificate of Analysis (COA) documenting identity, purity, and key physical-chemical parameters is provided with each shipment to guarantee batch-to-batch consistency for your manufacturing process.

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 absorption of atmospheric moisture, which can affect purity and performance. Keep away from incompatible materials.
