Description

Cuprate(5-), [[3,3'-Methylenebis[6-[[3- [(2,4-Disulfophenyl)Azo]-2,4-Dihydroxyphenyl]Azo ]Benzoato]](7-)]-, Pentasodium is a high-purity, complex azo dye-based copper salt designed for advanced industrial applications. This compound is valued for its strong chelating properties and intense coloration, making it a critical component in specialized formulations. It is primarily utilized by manufacturers in the textile, analytical chemistry, and specialty pigment sectors requiring precise and stable colorants or metal-complexing agents.

Application

• Textile Dyeing and Printing: As a high-performance metal-complex dye for synthetic fibers like nylon and polyamide, providing excellent wash and light fastness.
• Analytical Reagent: Used as a specific colorimetric indicator or chelating agent in complexometric titrations and metal ion detection assays.
• Specialty Pigments and Inks: A key intermediate for manufacturing high-stability, organic-based pigments used in industrial inks, coatings, and plastics.
• Catalyst Synthesis: Serves as a precursor or ligand in the preparation of specialized copper-based catalysts for organic synthesis.
• Biological Staining: Potential application in histological stains for microscopy due to its strong metal-binding and color properties.
• Photographic Sensitizers: Used in niche photographic and imaging technologies as a light-sensitive compound.
