For industrial chemists, process engineers, and procurement specialists, understanding the precise specifications of chemical raw materials is fundamental to successful application. Sodium Allyl Sulfonate (SAS), known by its CAS number 2495-39-8, is a chemical intermediate and additive whose performance is directly tied to its purity and physical characteristics. NINGBO INNO PHARMCHEM CO., LTD. ensures that its supply of SAS meets stringent quality benchmarks. This article outlines the key properties and specifications that make SAS a valuable industrial chemical.

Sodium Allyl Sulfonate is typically supplied as a liquid, often as a 35% aqueous solution. Its appearance is described as a clear, light yellow to yellow transparent liquid, which is indicative of its purity. The pH of a typical solution usually falls within the range of 6.5 to 9.0, maintaining a near-neutral environment. The density of the 35% solution is generally between 1.20 to 1.28 g/cm³ at 20ºC. These physical parameters are crucial for accurate handling, storage, and dosage calculations in industrial processes like nickel electroplating.

The chemical composition of SAS is also critical. The effective content of Sodium Allyl Sulfonate in a solution is a key indicator of its concentration and thus its efficacy in applications such as brightening in nickel plating baths or as a monomer in polymer synthesis. For example, in plating baths, dosages are often specified in grams per liter (g/L), making the precise concentration of SAS vital for achieving optimal results, such as improved metal distribution and ductility. The formula, C3H5NaO3S, and molecular weight of approximately 144.12 g/mol, are fundamental identifiers.

When considering SAS for its role as a monomer in acrylic fiber production or water treatment polymers, the purity of the product is paramount. Impurities such as sodium chloride (NaCl) or sodium sulfite (Na2SO3) can affect polymerization rates and the final properties of the polymers. Suppliers like NINGBO INNO PHARMCHEM CO., LTD. carefully control these impurity levels, often specifying maximum limits for NaCl (e.g., 4.5%) and other potential contaminants, ensuring consistent performance in sensitive applications.

The storage conditions for Sodium Allyl Sulfonate are also important to maintain its quality. It is typically recommended to store the product sealed in a cool and dry place. This prevents degradation and maintains its stability for extended periods. NINGBO INNO PHARMCHEM CO., LTD. provides comprehensive technical data sheets and guidance on safe handling and storage to ensure that clients can maximize the benefits of SAS in their operations.

In summary, the precise physical and chemical specifications of Sodium Allyl Sulfonate are key to its successful application in demanding industries. NINGBO INNO PHARMCHEM CO., LTD. is committed to delivering SAS that consistently meets these critical parameters, supporting advancements in electroplating, textiles, water treatment, and beyond.
