Description

1-Amino-4-[[4-(Benzoylamino)-3-Sulfophenyl]Amino]-9,10-Dihydro-9,10-Dioxo-2-Anthracenesulfonic Acid Disodium Salt is a high-purity, water-soluble anthraquinone derivative primarily utilized as a key intermediate in the synthesis of specialized dyes and pigments. Its molecular structure, featuring multiple sulfonic acid groups, provides excellent solubility and chromophoric properties critical for achieving vibrant and stable colors. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce high-performance colorants with specific fastness and application characteristics.

Application

• Primary Intermediate for Dye Synthesis: A crucial building block for manufacturing acid dyes, reactive dyes, and disperse dyes used in textile coloring.
• Specialty Pigment Production: Used in the synthesis of high-performance organic pigments for inks, coatings, and plastics requiring specific color strength and stability.
• Laboratory Research & Development: Serves as a reference standard and starting material in R&D for novel chromophores and functional dyes.
• Functional Material Synthesis: Potential intermediate in the development of dyes for non-textile applications, such as sensitizers for dye-sensitized solar cells (DSSCs) or biological stains.
