For professionals in the chemical industry, a clear understanding of the specifications and procurement pathways for essential intermediates is vital. Benzenesulfonylsulfanylsulfonylbenzene, bearing the CAS number 4388-22-1, is one such compound that requires careful consideration regarding its properties and how to source it effectively. This article provides an in-depth look at its technical details and procurement best practices.

The core specifications for Benzenesulfonylsulfanylsulfonylbenzene typically include its CAS RN (4388-22-1), molecular formula (C12H10O4S3), and molecular weight, which is approximately 314.39 g/mol. Purity is a critical parameter, often cited as 95% minimum by HPLC. The physical form is commonly described as an off-white to pink powder or crystals, indicating its solid state at room temperature. Key physical constants like melting point (129-134°C), boiling point (505.8°C at 760 mmHg), and flash point (259.7°C) provide further insight into its behavior and handling requirements. When looking to buy, these details are crucial for ensuring the material meets application needs.

Procuring Benzenesulfonylsulfanylsulfonylbenzene involves identifying reliable manufacturers and suppliers. Companies that specialize in organic chemistry and fine chemical intermediates, especially those with a strong presence in China, are often excellent sources. When sourcing, it is recommended to request a Certificate of Analysis (CoA) with each batch to verify purity and specifications. Understanding the storage conditions, typically recommended as cool, dry, and in a tightly closed container, is also important for maintaining product integrity post-purchase. Stability under normal temperatures and pressures is a significant advantage for handling and storage.

For businesses planning to purchase this intermediate, considering the packaging options is also relevant. Suppliers commonly offer various sizes, from grams for laboratory research to kilograms for pilot-scale or industrial production. This flexibility allows buyers to procure the exact quantity needed, optimizing cost and minimizing waste. Engaging with a manufacturer that can provide consistent supply and competitive pricing is key to establishing a strong supply chain for Benzenesulfonylsulfanylsulfonylbenzene.

In conclusion, Benzenesulfonylsulfanylsulfonylbenzene (CAS 4388-22-1) is a well-characterized organic intermediate with defined specifications and applications. By understanding its properties and engaging with reputable manufacturers, procurement specialists can ensure a reliable and efficient supply. This focus on detail is essential for successful R&D and manufacturing operations.
