Description
Cuprate, [μ-[[3,3'-Azoxybis[6-[2-[4-[[3-Hydroxy-4-[(2-Hydroxy-5-Sulfophenyl) Azo]Phenyl]Azo]-2-Sulfophenyl] Ethenyl] Benzenesulfonato]]]]Di-, Hexasodium is a complex, water-soluble azo dye complex containing copper. This compound matters for its ability to provide intense and stable coloration, particularly in demanding industrial environments where other dyes may fade or degrade. It is primarily needed by manufacturers in the textile, leather, and specialty ink industries seeking high-performance colorants for synthetic fibers and other materials.
Application
- Dyeing of Synthetic Fibers: Primary application for coloring polyamide (nylon), polyester, and acrylic fibers, offering excellent wash and light fastness.
- Leather Finishing: Used in the dyeing process for leather goods, providing deep, uniform shades.
- Inkjet Inks: A key component in the formulation of industrial and specialty inkjet inks requiring specific color properties and stability.
- Paper Coloration: Employed in the production of specialty colored papers and boards.
- Biological Staining: Potential use as a histological stain in laboratory settings due to its metal-complex structure.
- Plastics and Polymers: For mass coloration of certain plastics during the manufacturing process.

Quality Control
Our azo dye complexes are manufactured under a strict quality management system. Each batch undergoes rigorous testing for color strength, purity, solubility, and heavy metal content to ensure consistency and performance. Certificates of Analysis (COA) detailing specifications such as assay, shade, and fastness properties are available upon request to support your quality assurance protocols.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
