Used primarily as a key intermediate in organic synthesis, especially in the pharmaceutical industry. It enables the introduction of cyclopropyl groups into complex molecules, which can enhance metabolic stability and bioavailability of drug candidates. Commonly employed in the preparation of protease inhibitors and antiviral agents. Its high reactivity with nucleophiles makes it valuable for forming carbamate and ester derivatives under controlled conditions. Due to its sensitivity and reactivity, it is typically handled in anhydrous environments and used in low-temperature reactions to ensure selectivity and safety.
