Description

Trisodium 4-(Acetylamino)-6-[[5-[(2-Bromo-1-Oxoallyl)Amino]-2-Sulphonatophenyl]Azo]-5-Hydroxynaphthalene-1,7-Disulphonate is a high-purity, water-soluble reactive dye intermediate essential for producing vivid and durable colorants. Its complex molecular structure, featuring multiple sulphonate groups and a reactive bromoacrylamide moiety, enables strong covalent bonding with textile fibers like cotton and nylon, ensuring excellent wash and light fastness. This compound is a critical raw material for manufacturers of reactive dyes and specialty pigments targeting the textile, ink, and advanced material coating industries globally.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-performance reactive dyes used in textile dyeing and printing, particularly for cellulosic fibers.
• Specialty Pigment Manufacturing: Used in the production of complex organic pigments for inks, coatings, and plastics requiring specific color properties and stability.
• Research & Development: Serves as a standard or experimental compound in R&D labs for developing new chromophores and studying azo dye chemistry.
• Functional Material Synthesis: Potential use in creating dyes for non-textile applications, such as sensitizers in dye-sensitized solar cells (DSSCs) or biological stains.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and high chemical purity. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 to prevent absorption of atmospheric moisture, which can affect product stability and performance.
