β-Propiolactone(CAT: R000383) is a highly reactive four-membered lactone with the molecular formula C₃H₄O₂, known for its strained ring structure and potent alkylating properties. It is a colorless liquid with a slightly sweet odor and is completely miscible with water. In research, β-propiolactone is used as an intermediate in the synthesis of various chemicals, including acrylic acid derivatives, and as a sterilizing or inactivating agent for viruses, bacteria, and enzymes in vaccine preparation and laboratory decontamination. Due to its strong reactivity with nucleophiles, it readily undergoes ring-opening polymerization and hydrolysis.
