Description

Copper, 2,2'-[Carbonylbis[Imino(1-Hydroxy-3-Sulfo-6,2-Naphthalenediyl)Azo]]Bis[Benzoic Acid] Complex is a high-performance, water-soluble metal complex dye. This compound is valued for its strong chelation with copper, providing excellent stability and vivid coloration. It is primarily sought after by manufacturers in the textile, leather, and specialty ink industries for its durable and consistent dyeing properties.

Application

• Textile Dyeing: Used as a key colorant for dyeing natural and synthetic fibers, particularly where wash-fastness and light-fastness are critical.
• Leather Finishing: Applied in the dyeing and finishing of leather goods to achieve deep, uniform colors with good adhesion.
• Ink Formulation: Serves as a pigment in the production of specialty inks for packaging, security printing, and other industrial applications.
• Paper Coloration: Employed in the manufacturing of colored papers and paper products requiring high color strength.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its metal-complex structure.
• Functional Material Precursor: Investigated for use in the synthesis of advanced materials, including sensors and catalysts.

Quality Control

Our production of Copper, 2,2'-[Carbonylbis[Imino(1-Hydroxy-3-Sulfo-6,2-Naphthalenediyl)Azo]]Bis[Benzoic Acid] Complex adheres to stringent quality protocols. Each batch undergoes comprehensive analysis to ensure consistent purity, color strength, and metal content. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
