Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain central nervous system agents and antidepressants. It serves as a building block in organic reactions where a chlorinated cyclic ketone is required to form more complex molecular structures. Its reactivity allows for functional group transformations, such as nucleophilic substitution or reduction, enabling the development of active drug compounds. Also utilized in research settings for the preparation of novel heterocyclic compounds with potential biological activity.
