Description

Cuprate(4-), [3-carboxy-1-[4-[[3-[[[(2-carboxy-5-sulfophenyl) azo] phenylmethyl]azo]-2-hydroxy-5-sulfophenyl] amino]-6-[(2-chloro-5-sulfophenyl)amino]-1,3,5-triazin-2-yl]pyridiniumato(7-)]-, trisodium hydrogen is a high-purity, complex copper-based azo dye intermediate. This compound is critical for synthesizing specialized dyes and pigments with enhanced color fastness and specific functional properties. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Primary Intermediate for Reactive Dyes: Synthesis of high-quality reactive dyes for cotton and cellulose fibers, providing excellent wash and light fastness.
• Specialty Pigment Manufacturing: Used in the production of complex organic pigments for inks, coatings, and plastics requiring specific hue and stability.
• Functional Dye Synthesis: Key building block for creating dyes with specialized applications, such as those used in optical data storage or laser marking.
• Textile Colorant Production: Essential for manufacturing advanced textile colorants used in demanding apparel and technical textile applications.
• Research & Development: Serves as a valuable reference standard and starting material in chemical R&D for novel chromophores and metal-complex dyes.

Quality Control

Our Cuprate(4-) trisodium hydrogen intermediate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including HPLC and spectrophotometry. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
