For businesses in the chemical industry, understanding the precise specifications of raw materials is fundamental to successful procurement and application. Sodium 4-Fluorobenzenesulfinate (CAS 824-80-6) is a chemical intermediate with specific quality parameters that directly impact its performance in various industrial processes, from pharmaceutical synthesis to fine chemical manufacturing. Procurement managers and research scientists often seek detailed information on assay, appearance, and impurity levels when looking to buy.

The appearance of Sodium 4-Fluorobenzenesulfinate is typically described as a white crystalline solid. This physical characteristic is the first indicator of product quality. Beyond appearance, the assay purity, commonly ranging from 95% to 99.9% depending on the grade, is a critical factor. A higher assay means fewer impurities, which is crucial for sensitive applications where side reactions can compromise the final product. Buyers often search for 'high purity Sodium 4-Fluorobenzenesulfinate supplier' or 'CAS 824-80-6 assay specification'.

Furthermore, impurity profiles are essential. Specifications often list limits for related substances like Benzene sulfinic acid sodium and 4Fluoro-benzenesulfonic acid. For those looking to purchase this intermediate, understanding these limits and how they are tested (e.g., by HPLC) provides confidence in the product's suitability for their specific synthetic routes. Manufacturers in China are frequently a primary source for these intermediates, offering competitive pricing and accessible product data.

When considering a purchase, it's also important to note packaging and storage conditions. Typically packed in 25kg drums, Sodium 4-Fluorobenzenesulfinate requires storage in a cool, dry place. Reliable suppliers will provide comprehensive technical data sheets (TDS) and Certificates of Analysis (COA) upon request. Engaging with a manufacturer for a quote will usually include details on these specifications, helping buyers make informed decisions about where to buy.

In conclusion, a thorough understanding of the specifications for Sodium 4-Fluorobenzenesulfinate is vital for effective industrial procurement. By focusing on assay, impurity levels, and supplier reliability, companies can ensure they acquire the highest quality intermediate for their manufacturing and research needs.
