Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and anti-inflammatory agents. It serves as a building block in organic reactions where amide and chloro functionalities allow for further chemical modifications. Commonly employed in the development of active pharmaceutical ingredients (APIs) due to its reactivity and structural properties. Also utilized in research settings for designing novel bioactive molecules and in the preparation of analogs for structure-activity relationship (SAR) studies.
