Description

1,4-Diamino-9,10-Dihydro-9,10-Dioxoanthracene-2,6-Disulfonic Acid Disodium Salt is a high-purity, water-soluble anthraquinone derivative valued for its role as a key intermediate in the synthesis of vibrant and durable dyes and pigments. Its disulfonic acid sodium salt form provides excellent solubility and reactivity, making it a critical building block for advanced colorants. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce high-performance dyes with specific chromatic and fastness properties.

Application

• Primary Intermediate for Dyes & Pigments: A crucial precursor in the synthesis of acid dyes, reactive dyes, and disperse dyes, particularly for coloring polyamide fibers like wool and nylon.
• Textile Industry: Used to manufacture dyes that offer bright shades, excellent wash-fastness, and good light-fastness on various natural and synthetic fabrics.
• Ink Manufacturing: Serves as an intermediate for producing colorants used in inks for packaging, printing, and writing instruments.
• Specialty Chemical Synthesis: Acts as a versatile building block in organic synthesis for creating more complex anthraquinone-based compounds with specialized functions.
• Research & Development: Utilized in laboratories for developing new chromophores, studying dye chemistry, and creating novel materials with specific optical properties.
