Description

Cuprate(3-), [μ-[3-[[5-(aminosulfonyl)-2-hydroxyphenyl]azo]-4-hydroxy-7-[[[[5-hydroxy-6-[(2-hydroxy-5-sulfophenyl)azo]-7-sulfo-2-naphthalenyl]amino]carbonyl]amino]-2-naphthalenesulfonato(7-)]]di-, trisodium is a complex, high-purity azo dye intermediate and coordination compound. This product is critical for synthesizing specialized dyes and pigments with enhanced color fastness and specific chelating properties. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Primary Intermediate for Metal-Complex Dyes: Used in the synthesis of high-grade, lightfast, and washfast dyes for textiles, leather, and automotive fabrics.
• Specialty Pigment Manufacturing: Serves as a key precursor for producing complex inorganic color pigments (CICPs) and other high-performance pigments.
• Analytical Chemistry Reagent: Employed as a chelating agent or colorimetric indicator in specific analytical and research applications.
• Functional Dye Synthesis: Used in the development of dyes for non-textile applications, such as in inks, coatings, and imaging technologies.

Quality Control

Our production of this advanced intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and purity for downstream synthesis. Quality is verified through analytical techniques including HPLC, UV-Vis spectroscopy, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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). This compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
