Description

Ferrate(5-), bis[4-[[2,4-dihydroxy-5-[ (2-methoxyphenyl)azo]-3-[[4-(phenylamino)-3-sulfophenyl ]azo]phenyl]azo]-3-hydroxy-7-nitro-1-naphthalenesulfonat o(4-)]-, sodium is a complex, high-purity azo dye intermediate essential for producing vivid and stable colorants. This compound matters for its role in synthesizing specialized dyes with excellent lightfastness and wash-fastness properties for demanding applications. It is primarily needed by manufacturers in the textile, leather, ink, and specialty pigments industries seeking to develop high-performance coloring agents. The product is supplied under stringent quality control to ensure batch-to-batch consistency for industrial synthesis.

Application

• Textile Dyeing: A key intermediate for the synthesis of high-grade, wash-fast azo dyes used on cotton, wool, and synthetic fibers.
• Leather Coloring: Used in the production of dyes for imparting deep, uniform colors to leather goods with good adhesion.
• Ink Manufacturing: Serves as a precursor for pigments in printing inks, including those for packaging and publications.
• Specialty Pigments: Employed in the creation of complex organic pigments for plastics, coatings, and artist colors.
• Research & Development: Used in chemical research for developing novel chromophores and studying dye-sensitized systems.
• Paper Staining: Can be utilized in the synthesis of dyes for specialty paper products requiring specific color tones.

Quality Control

Our production of this azo dye intermediate adheres to rigorous quality testing protocols to ensure it meets the high-purity standards required for sensitive synthesis processes. Each batch is analyzed to confirm identity, purity, and the absence of critical impurities that could affect downstream dye performance. A Certificate of Analysis (COA) detailing specific test results is 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, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
