Description

4-[[3-(Acetylamino)Phenyl]Amino]-1-Amino-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonic Acid is a specialized anthraquinone derivative, valued for its role as a key intermediate in the synthesis of high-performance dyes and pigments. This compound matters for its ability to impart specific color properties and stability to the final products. It is primarily needed by manufacturers in the dye and pigment industry, as well as by research institutions developing advanced colorants and functional materials.

Application

• Primary intermediate for the synthesis of anthraquinone-based dyes, particularly for textile applications.
• Key building block in the production of specialized pigments used in inks, coatings, and plastics.
• Research and development of novel functional dyes for non-textile applications, such as in electronics or sensors.
• Used in the preparation of colorants for synthetic fibers like polyester and nylon.
• Potential intermediate for photographic dyes or other light-sensitive materials.
• Starting material for fine chemical synthesis in academic and industrial research laboratories.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We implement strict in-process controls and final product verification to guarantee batch-to-batch consistency and purity. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and physical characteristics are available upon request.

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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
