Description

2-[[5-Cyano-2,6-Bis[(3-Hydroxypropyl)Amino]-4-Methyl-3-Pyridyl]Azo]-5-[[2-(Sulphooxy)Ethyl]Sulphonyl]Benzenesulphonic Acid, Sodium Salt is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. This compound is valued for its ability to impart bright, wash-fast colors when covalently bonded to cellulosic fibers like cotton and viscose. It is a critical raw material for manufacturers of reactive dyes and specialty colorants targeting the textile, ink, and potentially biomedical staining industries.

Application

• Primary Intermediate for Reactive Dyes: Serves as the key chromophore in the synthesis of high-performance reactive dyes for cotton, linen, and other cellulosic fabrics.
• Textile Dyeing and Printing: Used in formulations for exhaust dyeing, continuous dyeing, and printing processes, offering excellent wet fastness properties.
• Inkjet Ink Formulation: Potential application in the production of specialized colorants for high-quality textile or industrial inkjet inks.
• Research & Development: Employed in chemical R&D for developing novel azo dyes with specific lightfastness and solubility characteristics.
• Specialty Colorants: Can be used to create custom colors for niche applications in paper, leather, or as a biochemical stain.

Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance in downstream synthesis. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance systems.

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 after initial use to prevent moisture absorption, which can affect stability and handling properties.
