Description

Cuprate(1-), [3-[[[(3-Amino-4-Nitrophenyl) Azo]-2,4-Dihydroxyphenyl]Azo]-4-Hydroxybenzenesulfonato (3-)]-, Sodium is a complex azo-copper coordination compound, also known as a copper complex dye. This product matters for its ability to provide enhanced color fastness and stability compared to conventional azo dyes, making it valuable for demanding applications. It is primarily needed by manufacturers in the textile, leather, and specialty ink industries seeking durable and vibrant coloration.

Application

• Textile Dyeing: Used for dyeing natural and synthetic fibers, particularly where high light and wash fastness are required.
• Leather Finishing: Applied in the coloration of leather goods, providing rich, penetrating shades with good rub resistance.
• Specialty Inks: Serves as a colorant in high-performance inks for packaging, security printing, or other niche applications.
• Paper Coloration: Employed in the production of specialty colored papers and boards.
• Biological Staining (Research Grade): Potential use as a histological or cytological stain in laboratory settings.
• Functional Material Synthesis: May be used as a precursor or intermediate in the synthesis of metal-organic frameworks (MOFs) or other coordination polymers.
