Description
Cuprate(4-), [5-(acetylamino)-4-hydroxy-3-[[5-hydroxy-6-[[2-hydroxy-5-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]azo]-7-sulfo-2-naphthalenyl]azo]-2,7-naphthalenedisulfonato(6-)]-, sodium is a complex, water-soluble copper-containing azo dye. This compound matters for its specific chelating properties and intense color, which are critical for high-performance applications requiring precise metal coordination and stable coloration. It is primarily needed by manufacturers in the textile, specialty ink, and analytical reagent industries.
Application
- Textile Dyeing: As a specialized dye for natural and synthetic fibers, particularly where copper complexation enhances color fastness and light stability.
- Functional Inks: Used in the formulation of security inks, color filters, and other high-value printing applications requiring specific spectral properties.
- Analytical Chemistry: Acts as a colorimetric reagent or indicator in complexometric titrations and metal ion detection assays.
- Research & Development: Serves as a key intermediate or reference standard in the synthesis of novel coordination compounds and dyes.
- Catalyst Preparation: Potential use as a precursor for copper-based catalysts in organic synthesis.
