Used as a key intermediate in the synthesis of complex organic molecules, particularly in the pharmaceutical industry. It plays a role in the development of active pharmaceutical ingredients (APIs) due to its reactive methanesulfonate group, which facilitates further chemical modifications. Additionally, it is employed in research settings for constructing spirocyclic compounds, which are valuable in drug discovery for their unique structural properties and potential biological activity. Its application extends to material science, where it contributes to the creation of specialized polymers and advanced materials with tailored properties.
