Description

1-Amino-9,10-Dihydro-9,10-Dioxo-4-[3-[[2-(Phosphonooxy)Ethyl]Sulphonyl]Anilino]Anthracene-2-Sulphonic Acid, Sodium Salt is a high-purity, water-soluble anthraquinone derivative distinguished by its sulfonic acid and phosphonooxyethylsulfonyl anilino functional groups. This compound is engineered to deliver exceptional performance as a key intermediate in the synthesis of advanced, high-value dyes and pigments. It is critically important for manufacturers in the textile, ink, and specialty chemical industries seeking to develop products with enhanced color fastness, solubility, and application properties.

Application

• Primary intermediate for the synthesis of reactive and acid dyes for textile fibers, particularly wool, silk, and nylon.
• Key building block in the production of high-performance pigments for inks, coatings, and plastics.
• Used in research and development of novel chromophores and functional dyes for optical applications.
• Potential intermediate for dye-sensitized solar cells (DSSCs) and other photoelectrochemical systems.
• Specialty chemical precursor for analytical reagents and biological staining agents.
• Development of colorants for specialty papers and security printing applications.

Quality Control

Our production of this anthraquinone intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and high chemical purity. Every lot is analyzed using advanced techniques including HPLC and spectroscopic methods to confirm identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles is provided with each shipment to support your quality assurance and R&D processes.

Storage

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