Description

Disodium 3-[[4-[(4-Amino-9,10-Dihydro-9,10-Dioxo-3-Sulphonato-1-Anthryl)Amino]Phenoxy]Sulphonyl]Benzoate is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its role in synthesizing vibrant and stable dyes and pigments, particularly for demanding technical applications. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Textile Dye Intermediate: A key precursor for synthesizing reactive and acid dyes used in coloring natural and synthetic fibers like cotton, wool, and nylon.
• Inkjet Ink Formulation: Used in the production of specialized dyes for high-quality photographic and graphic arts inks, offering excellent color strength and stability.
• Functional Dye Synthesis: Serves as a building block for dyes used in non-textile applications, including lasers, optical data storage, and liquid crystal displays (LCDs).
• Biological Staining: Potential use in the development of histological stains and fluorescent probes for laboratory and diagnostic applications.
• Paper Coloring: Employed in the manufacture of dyes for high-grade, color-fast paper products.
• Research & Development: Used as a standard or intermediate in chemical research for developing new chromophores and functional materials.
