For any chemical used in industrial or research settings, understanding its purity and key specifications is the first step towards successful application. Sodium Anthraquinone-2-sulfonate (CAS 131-08-8) is no exception. As a critical component in processes like alkaline pulping and as an intermediate in various syntheses, its quality directly impacts process efficiency and final product integrity.

The purity of Sodium Anthraquinone-2-sulfonate is typically measured using techniques such as High-Performance Liquid Chromatography (HPLC) or titration. Manufacturers often offer grades with purities ranging from 90% to over 99%, depending on the intended application. For demanding processes where even minor impurities can cause significant disruptions, sourcing a higher-purity grade is essential. When you buy Sodium Anthraquinone-2-sulfonate, always verify the stated purity and the analytical methods used to confirm it.

Key specifications also include physical characteristics like appearance (often a yellow crystalline powder) and solubility. For its primary use as a pulping additive, its water solubility is crucial for effective dispersion within the pulping liquor. Other important parameters might include moisture content and the presence of specific by-products from the manufacturing process. A reputable supplier, like a dedicated manufacturer in China, will provide detailed Certificates of Analysis (CoA) that outline these specifications for each lot purchased.

When making a purchase decision, it’s important for procurement managers and R&D scientists to clearly define their requirements. This includes specifying the desired purity, quantity, and any particular analytical data needed.
