Description

Trisodium 5-Amino-8-[[4-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-3-Sulphonatophenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracenedisulphonate is a high-purity, reactive anthraquinone derivative dye intermediate. Its core value lies in its ability to form covalent bonds with substrates, offering excellent wash and light fastness properties for demanding applications. This compound is essential for manufacturers in the textile, specialty ink, and advanced material sectors seeking to produce high-performance, colorfast dyes and pigments.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-grade reactive dyes, particularly for cellulose fibers like cotton and viscose, where it imparts brilliant blue to green shades.
• Textile Printing and Dyeing: Used in formulations for industrial textile printing inks and dye baths that require superior color yield and durability.
• Specialty Inks: Serves as a colorant precursor in the production of inks for security printing, packaging, and other applications demanding high chemical resistance.
• Functional Material Production: Employed in the synthesis of colored polymers, liquid crystal displays (LCDs), and other advanced materials where chromophore integration is needed.
• Research & Development: Used in chemical R&D laboratories for developing new chromophores, studying dye-substrate interactions, and creating novel colorants.
