Description

1-Amino-4-[(3-Amino-2-Methyl-5-Sulphophenyl)Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonic Acid is a high-purity, water-soluble anthraquinone derivative primarily used as a key intermediate in the synthesis of advanced dyes and pigments. Its molecular structure provides excellent chromophoric properties, making it essential for producing vivid and stable colors. This compound is critical for manufacturers in the textile, ink, and specialty chemical industries who require consistent quality and reliable supply for their production processes.

Application

• Primary Intermediate for Dyes & Pigments: Serves as a crucial building block in the synthesis of high-performance anthraquinone-based dyes, particularly for textile fibers like cotton, wool, and nylon.
• Textile Dye Manufacturing: Used in the production of acid dyes and reactive dyes known for their bright shades, good lightfastness, and wash-fastness properties.
• Specialty Ink Formulations: Employed in creating pigments for inks used in high-quality printing and packaging applications where color stability is paramount.
• Functional Dye Synthesis: Acts as a precursor for dyes used in more advanced applications, such as laser dyes, optical data storage media, and non-linear optical materials.
• Research & Development: Utilized in chemical R&D laboratories for developing novel chromophores and studying structure-property relationships in dye chemistry.
