Used as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a building block for introducing cyclopropyl-containing side chains into target molecules, which can enhance metabolic stability and binding affinity in drug candidates. Commonly employed in the development of bioactive compounds and medicinal agents where structural modification with a cyclopropyl group is required. Its sulfonate ester functionality makes it suitable for substitution reactions, enabling carbon-carbon or carbon-heteroatom bond formation under mild conditions.
