Description

Trisodium 1-amino-4-[[4-[[4-[[4-[(4-amino-9,10-dihydro-9,10-dioxo-3-sulphonato-1-anthryl)amino]phenyl]amino]-1,4-dioxobut-2-enyl]amino]-3-sulphonatophenyl]amino]-9,10-dihydro-9,10-dioxoanthracene-2-sulphonate is a high-purity, water-soluble anthraquinone derivative dye intermediate of significant commercial importance. It serves as a critical precursor for synthesizing high-performance dyes and pigments, valued for their excellent color fastness and stability. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce vibrant and durable colorants.

Application

• Textile Dyeing: A key intermediate for the synthesis of reactive and acid dyes used on cotton, wool, silk, and nylon fibers.
• Ink Manufacturing: Used in the production of high-quality pigments for printing inks, including inks for packaging and security applications.
• Functional Dyes: Serves as a building block for dyes used in non-textile applications, such as laser dyes, optical data storage, and liquid crystal displays (LCDs).
• Research & Development: Employed in academic and industrial R&D labs for developing novel chromophores and studying dye chemistry.
• Specialty Coatings: Used in the formulation of specialized coatings where specific color properties and lightfastness are required.
