Description

Disodium 1-Amino-4-[3-[[(3,6-Dichloropyridazin-4-Yl)Carbonyl]Amino]-2,4,6-Trimethyl-5-Sulphonatoanilino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its role as a key precursor in the synthesis of high-performance, reactive dyes and pigments, offering excellent color fastness and brightness. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing vibrant and durable colorants.

Application

• Primary Intermediate for Reactive Dyes: A critical building block in the synthesis of high-quality reactive dyes used for coloring cellulose fibers like cotton, viscose, and linen.
• Specialty Pigment Manufacturing: Used in the production of high-performance organic pigments for inks, coatings, and plastics that require superior color strength and stability.
• Textile Printing Inks: Serves as a key chromophore component in formulations for digital and screen textile printing, ensuring vivid and wash-fast prints.
• Research & Development: Employed in chemical R&D for developing novel dye structures and studying structure-property relationships in color chemistry.
• Functional Dye Synthesis: Potential use as a precursor for functional dyes applied in non-textile areas such as sensors or light-harvesting materials.
