1,3-Propanesultone (CAS 1120-71-4) is a compound of significant industrial interest, primarily due to its potent sulfonating capabilities. As a leading manufacturer and supplier of this chemical from China, we believe it's crucial for our B2B partners—procurement managers, R&D scientists, and formulators—to have a thorough understanding of its properties, specifications, and safe handling procedures. This knowledge ensures optimal utilization and workplace safety.

Key Chemical Properties and Specifications

At its core, 1,3-Propanesultone is a cyclic sulfonate ester with the molecular formula C3H6O3S. It is typically supplied as a colorless transparent liquid, though it can crystallize at lower temperatures, with a reported melting point around 31.2°C. Key specifications often include:

  • Assay/Purity: Typically ≥99.0% or higher, ensuring effectiveness in sensitive applications.
  • Appearance: Colorless transparent liquid.
  • Moisture Content: Kept to a minimum, usually less than 100 ppm, to prevent unwanted side reactions.
  • Acidity: Similarly, acidity levels are controlled to be below 100 ppm.
  • Refractive Index: A standard parameter for quality verification.

These properties make it an excellent sulfonating agent, capable of reacting with many compounds under mild conditions to introduce sulfonic acid groups, thereby modifying their characteristics like hydrophilicity and antistatic properties.

Safe Storage and Handling Practices

While highly effective, 1,3-Propanesultone requires careful handling. As a chemical intermediate, it necessitates proper storage in a well-ventilated, low-temperature, and dry warehouse. It should be stored separately from food raw materials, strong oxidants, and halogenated hydrocarbons to prevent any hazardous reactions. Personnel handling this material should use appropriate personal protective equipment (PPE), including gloves, eye protection, and protective clothing, and work in well-ventilated areas or fume hoods. Understanding these safety protocols is vital for anyone looking to buy 1,3-Propanesultone in bulk.
