1,3-Propanesultone（Cat No.:R007884）is a highly reactive cyclic sulfonate ester commonly used as an intermediate in the synthesis of sulfonic acid derivatives. It functions as a sulfoalkylating agent, introducing sulfonate groups into organic molecules, polymers, and pharmaceutical compounds. This compound is valuable in the production of zwitterionic surfactants, ion-exchange resins, and electrolyte additives for lithium-ion batteries. It appears as a colorless to pale yellow liquid or crystalline solid and is soluble in polar organic solvents. Due to its strong alkylating properties, it should be handled with care under controlled laboratory conditions.
