Description

Trisodium 4-[[6-[[4-Chloro-6-[(4-Methoxy-2-Sulphonatophenyl)Amino]-1,3,5-Triazin-2-Yl]Methylamino]-1-Hydroxy-3-Sulphonato-2-Naphthyl]Azo]Benzoate is a high-purity, water-soluble reactive dye intermediate essential for creating vibrant and wash-fast colors. Its complex molecular structure, featuring multiple sulphonate groups and a reactive triazine moiety, provides excellent substantivity and covalent bonding capabilities with cellulosic fibers. This compound is a critical raw material for manufacturers of textile dyes, specialty inks, and colorants requiring superior performance in demanding applications.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in the textile industry for cotton, viscose, and other cellulosic fibers.
• Specialty Ink Manufacturing: Used in the production of colorants for inks requiring high stability and color strength, particularly for jet printing and packaging.
• Leather Dyeing: Employed in the formulation of dyes for leather processing, offering good penetration and color fastness.
• Paper Coloring: Suitable for the coloration of specialty papers where bright, stable hues are required.
• Research & Development: Serves as a precise chemical entity for R&D laboratories developing new chromophores and studying dye-polymer interactions.
• Fine Chemical Synthesis: Acts as a sophisticated intermediate in the multi-step synthesis of complex organic molecules and functional dyes.

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 sealed when not in use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
