Description

1-Amino-4-[[3-[[N,n-Bis(2-Hydroxyethyl)Amino]Sulfonyl]Phenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulfonic Acid Sodium Salt is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its ability to impart a stable blue hue and its excellent reactivity for further chemical synthesis. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance dyes and pigments.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the synthesis of high-quality, fiber-reactive blue dyes for cotton and other cellulosic textiles.
• Specialty Ink Production: Used in the formulation of inks for jet printing, security printing, and other applications requiring specific color fastness and solubility.
• Functional Dye Synthesis: Serves as a precursor for dyes used in biological staining, liquid crystal displays (LCDs), and other advanced optical materials.
• Research & Development: Employed in academic and industrial R&D labs for developing novel chromophores and studying dye chemistry.
• Pigment Manufacturing: Can be processed into lake pigments for plastics, coatings, and other colored industrial products.
