Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and antipsychotic drugs. It serves as a building block in organic reactions where chlorinated ketones are required, enabling the formation of complex molecular structures. Its reactivity allows for functional group transformations, making it valuable in research and development within medicinal chemistry. Also utilized in the preparation of psychoactive substances in controlled laboratory settings, though not intended for direct therapeutic use.
