Sodium Allylsulfonate (SAS), identified by CAS number 2495-39-8, is a versatile organic chemical compound that serves as a crucial intermediate in numerous industrial syntheses. Understanding its fundamental properties and how it is produced provides valuable insight into its wide-ranging applications.

Chemically, Sodium Allylsulfonate is the sodium salt of allylsulfonic acid. It is typically characterized as a white crystalline powder or sometimes as a colorless to pale yellow liquid, depending on its form and purity. It exhibits good solubility in water and alcohol, which is advantageous for its use in aqueous formulations and reactions. The compound's molecular formula is C3H5NaO3S, with a molecular weight of approximately 144.13 g/mol. Its stability under various conditions, coupled with its reactive allyl group and sulfonic acid moiety, makes it an attractive building block for more complex molecules.

The synthesis of Sodium Allylsulfonate commonly involves the reaction between allyl chloride and sodium sulfite. This process, often carried out under controlled temperature and pH conditions, yields the desired product. Manufacturers continuously refine these processes to optimize yield, purity, and cost-effectiveness, ensuring a reliable supply chain for downstream industries.

As a chemical intermediate, Sodium Allylsulfonate's value lies in its ability to be incorporated into larger polymer structures or to modify the properties of existing materials. Its applications as a monomer in synthetic fibers, a brightener in electroplating, and an additive in water treatment and construction materials all stem from its unique chemical architecture. The presence of the sulfonate group imparts hydrophilic properties and allows for ionic interactions, while the allyl group provides a site for polymerization or further chemical modification. Manufacturers often source this compound from specialized chemical producers in China, recognizing the competitive pricing and quality standards available.

The comprehensive understanding of Sodium Allylsulfonate's properties and synthesis is key for chemists and engineers looking to leverage its potential in developing new materials and improving existing industrial processes.
