In the chemical industry, especially in the realm of dye manufacturing, quality assurance for intermediates is not merely a procedural step but a critical determinant of final product performance. Sodium Anthraquinone-2-Sulfonate (CAS 131-08-8) is a prime example of an intermediate where stringent quality control is indispensable. This article focuses on the key quality aspects that procurement managers and formulators should consider when purchasing this compound.

Sodium Anthraquinone-2-Sulfonate, recognized for its role in synthesizing a broad spectrum of dyes including anthraquinone acid, reactive, reduction, and disperse dyes, must meet precise specifications. The typical purity level of ≥98.5% is a primary indicator of quality. Beyond overall purity, specific parameters like moisture content (ideally ≤1.0%) and insoluble content (typically ≤0.5%) are crucial. These factors directly impact reaction efficiency, solubility, and the final color characteristics of the dyes produced. When you buy Sodium Anthraquinone-2-Sulfonate, always request the Certificate of Analysis (COA) to verify these critical metrics.

For those looking to purchase this chemical, understanding how to evaluate a Sodium Anthraquinone-2-Sulfonate supplier involves assessing their quality management systems. Reputable manufacturers will have robust testing protocols in place and can provide detailed documentation supporting their product quality. The price of Sodium Anthraquinone-2-Sulfonate should be considered in conjunction with these quality assurances. Investing in a higher-quality product from a reliable source often translates to fewer processing issues and better end-product results, ultimately offering better value.

When sourcing from international markets, particularly China, identifying a trustworthy Sodium Anthraquinone-2-Sulfonate manufacturer is key. Companies that adhere to international quality standards, such as ISO certifications, and have a transparent approach to product data are highly recommended. Furthermore, the ability to secure samples for preliminary testing is an important part of the buyer's due diligence process before committing to larger quantities.
