Description

Trisodium 5-[[9,10-Dihydro-8-Hydroxy-4-[(1-Methylethyl)Amino]-9,10-Dioxo-7-Sulphonato-1-Anthryl]Amino]Toluene-2,4-Disulphonate is a high-purity, water-soluble anthraquinone derivative dye intermediate, essential for producing vibrant and stable colorants. Its core value lies in its ability to impart strong, lightfast hues and serve as a key building block in the synthesis of specialized dyes and pigments. This compound is primarily needed by manufacturers in the textile, ink, and specialty chemical industries seeking reliable intermediates for high-performance color applications.

Application

• Textile Dye Intermediate: A critical 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 high-quality, color-fast pigments for industrial and commercial printing inks.
• Specialty Pigment Synthesis: Serves as a key intermediate for creating organic pigments with enhanced brightness and durability for plastics and coatings.
• Laboratory & Research: Employed as a standard or reagent in chemical research focused on dye chemistry, photochemistry, and material science.
• Functional Dye Production: Potential use in the synthesis of dyes for non-textile applications, such as in optical data storage or solar cells.
