Description

2-Anthracenesulfonic acid, 1-amino-4-[[3- [[4-chloro-6-[(3-sulfophenyl)amino] -1,3,5-triazin-2-yl]amino]-4-sulfophenyl]amino]-9,10-dihydro-9,10-dioxo-, monolithiumdisodium salt is a high-purity, water-soluble anthraquinone derivative engineered for advanced applications. This compound matters as a sophisticated intermediate or functional dye, offering precise chromophoric and chemical reactivity for demanding synthesis. It is primarily needed by manufacturers in the dye and pigment industry, as well as researchers developing specialty chemicals and functional materials.

Application

• Key Intermediate for Reactive Dyes: Serves as a critical building block in the synthesis of high-performance reactive dyes for textiles, particularly for cellulose fibers like cotton.
• Functional Dye Manufacturing: Used in the production of specialized anthraquinone-based dyes requiring specific solubility and color properties.
• Research & Development: Employed in academic and industrial R&D for developing new chromophores, photoactive materials, or chemical sensors.
• Specialty Chemical Synthesis: Acts as a multifunctional intermediate in organic synthesis for pharmaceuticals or advanced materials due to its sulfonic acid and amino groups.
• Ink Formulations: Potential use in formulating specialty inks where specific color fastness and solubility characteristics are required.
