China and Germany are the leading exporters of 1,3-Propane sultone (CAS 1120-71-4), accounting for the majority of global shipments in recent years, while the United States, South Korea, and Japan represent the largest importing markets. Trade volumes have remained relatively stable since 2022, with modest growth in Asian demand coinciding with steady 1,3-Propane sultone prices amid consistent industrial procurement for pharmaceutical and electrolyte applications.
1,3-Propane sultone is a colorless to pale yellow liquid at room temperature with a faint, chloroform-like odor; it has a melting point of approximately 20–22 °C and a boiling point of about 285 °C at atmospheric pressure. It is a cyclic sulfonic acid ester (sultone) and classified as a reactive organic intermediate. Primarily used as a sulfonating and alkylating agent, it serves as a key building block for synthesizing sulfobetaines, zwitterionic surfactants, and functionalized polymers. Its main applications are in the production of high-performance surfactants, corrosion inhibitors, and specialty monomers for coatings, oilfield chemicals, and water-treatment additives.
1,3-Propanesultone has been used in preparation of poly[2-ethynyl-N-(propylsulfonate)pyridinium betaine],novel poly(4-vinylpyridine) supported acidic ionic liquid catalyst,novel poly(4-vinylpyridine) supported acidic ionic liquid catalyst.
