Description

7-[[4-[(6-Ureido-1-hydroxy-3-sodiosulfo-2-naphthalenyl)azo]benzoyl]amino]-4-hydroxy-3-[[2-methyl-4-[(2-methyl-4-sodiosulfophenyl)azo]phenyl]azo]naphthalene-2-sulfonic acid sodium salt is a high-purity, complex azo dye intermediate essential for producing vibrant and stable colorants. This compound matters for its role in synthesizing high-performance dyes with excellent light and wash fastness properties. It is primarily needed by manufacturers in the textile, leather, and specialty ink industries seeking to develop advanced coloring solutions.

Application

• Textile Dyeing: A key intermediate for the synthesis of reactive and direct dyes used on cotton, wool, and nylon fibers.
• Leather Finishing: Used in the production of dyes for imparting deep, uniform colors to leather goods.
• Specialty Inks: Serves as a precursor for pigments in high-quality printing inks, including for packaging and security applications.
• Paper Coloring: Employed in the manufacture of dyes for coloring paper and paperboard products.
• Research & Development: Used as a standard or building block in chemical research for developing new chromophores and functional dyes.
• Industrial Pigments: A critical component in the synthesis of complex organic pigments for plastics and coatings.

Quality Control

Our production of 7-[[4-[(6-Ureido-1-hydroxy-3-sodiosulfo-2-naphthalenyl)azo]benzoyl]amino]-4-hydroxy-3-[[2-methyl-4-[(2-methyl-4-sodiosulfophenyl)azo]phenyl]azo]naphthalene-2-sulfonic acid sodium salt adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and chemical identity. Certificates of Analysis (COA) detailing assay, impurity profile, and physical specifications are available upon request to support your quality assurance processes.

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). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed when not in use to prevent degradation and moisture absorption.
