Description

Trisodium 4-amino-3-[[4-[[4-[[4-[[2-(diethylamino)ethyl]amino]-2-hydroxyphenyl]azo]phenyl]amino]-3-sulphonatophenyl]azo]-5-hydroxy-6-(phenylazo)naphthalene-2,7-disulphonate is a high-purity, water-soluble polyazo dye intermediate known for its complex molecular structure and functional versatility. This compound is critical for synthesizing advanced dyes and pigments that require specific color fastness, stability, and compatibility with various substrates. It is primarily sought by manufacturers in the textile, ink, and specialty chemical industries for developing high-performance colorants.

Application

• Primary intermediate for the synthesis of high-grade, metal-complex azo dyes used in textile dyeing and printing.
• Key component in the production of specialized pigments for inks, including those used in packaging and security printing.
• Used in the formulation of functional dyes for non-textile applications such as lasers, optical data storage, and liquid crystal displays (LCDs).
• Employed in research and development for creating novel colorants with enhanced lightfastness and chemical resistance.
• Potential use as a staining agent or colorimetric indicator in analytical chemistry and biological research.

Quality Control

Our production of this advanced dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques to confirm identity and quantify key impurities. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every 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 nature, the container must be kept sealed to prevent moisture absorption, which can affect product stability and handling properties.
