Used 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 the chloro and methoxy functional groups allow for further chemical modifications. Commonly employed in the development of active pharmaceutical ingredients (APIs) due to its reactive ketone group and aromatic structure, which facilitate coupling and substitution reactions. Also utilized in research settings for the preparation of analog compounds in medicinal chemistry.
