1,4-Butanesultone is a cyclic sulfonic ester widely used as a key intermediate in lithium-ion battery electrolytes, pharmaceutical synthesis (e.g., busulfan), and specialty surfactants. This compound exhibits a melting point of 12-15°C and boiling point of 134-136°C (0.53kPa), with a density of 1.331 g/cm³ (20°C) and refractive index of 1.464. It shows moderate water solubility (54g/L at 20°C) but decomposes in aqueous solutions. Storage requires airtight containers below 30°C with moisture protection. Safety precautions include skin/eye protection (GHS Category 2) due to its irritant properties and potential carcinogenicity (GHS Category 1B).
