Sodium ethenesulfonate(CAS: 3039-83-6)

Sodium ethenesulfonate is an organosulfur compound with the chemical formula C2H4NaO2S. It is a white crystalline powder that is highly soluble in water. This compound is commonly used as a sulfonating agent due to its ability to introduce sulfonate groups into organic molecules. Its structure consists of an ethylene group linked to a sulfonate functional group, making it valuable in chemical synthesis and industrial applications.

Sodium ethenesulfonate is primarily used in pharmaceuticals for synthesizing sulfonamide drugs, in the chemical industry as a precursor for dyes and surfactants, and in research for organic reactions. It also finds applications in food processing as a stabilizer and in polymer science for modifying material properties. Its versatility as a sulfonating agent makes it essential in various industrial and scientific processes.

Sodium ethenesulfonate is generally considered safe when handled according to standard laboratory and industrial protocols. However, it may cause skin and eye irritation, and its vapors can be harmful if inhaled. Safety data sheets (SDS) recommend using appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. It is classified as a corrosive substance, so proper ventilation and containment are necessary to ensure safe handling and compliance with OSHA and EPA regulations.

Sodium ethenesulfonate should be stored in a cool, dry place away from moisture and direct light. It requires airtight containers made of non-reactive materials like glass or HDPE to maintain stability. Storage conditions should be controlled at temperatures below 25°C and humidity levels under 60%. Always keep it in a well-ventilated area and label containers clearly to prevent accidental exposure and ensure long-term preservation.
