Description

Disodium 3-[(4-Amino-9,10-Dihydro-9,10-Dioxo-3-Sulpho-1-Anthracenyl)Amino]Benzoate is a high-purity, water-soluble anthraquinone derivative valued for its role as a key intermediate in the synthesis of specialized dyes and pigments. Its molecular structure provides excellent chromophoric properties, making it essential for producing vivid and stable colors. This compound is primarily sought by manufacturers in the textile, ink, and specialty chemical industries for developing advanced colorants and functional materials.

Application

• Textile Dye Intermediate: A crucial precursor for synthesizing reactive and acid dyes used in coloring natural and synthetic fibers like cotton, wool, and nylon.
• Inkjet Ink Formulation: Used in the production of high-performance pigment-based inks, contributing to color strength, stability, and print quality.
• Functional Dye Synthesis: Serves as a building block for creating dyes with specific optical properties for applications in lasers, sensors, or liquid crystal displays (LCDs).
• Leather and Paper Coloring: Employed in the manufacture of dyes for the uniform and durable coloration of leather goods and specialty papers.
• Research & Development: Utilized in academic and industrial R&D labs for exploring new chromophores, photoactive compounds, and advanced material science applications.
• Biological Staining Agent: Potential use as a specialized stain in histological or microbiological applications due to its anthraquinone core.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
