Used as an intermediate in the synthesis of anti-inflammatory agents, particularly in the preparation of fenbufen and related nonsteroidal anti-inflammatory drugs (NSAIDs). It plays a key role in organic transformations where the chloroacetamide group facilitates ring closure or functional group modification. Also employed in research settings for developing novel heterocyclic compounds with potential biological activity. Its structure supports the formation of benzoxazepine derivatives through cyclization reactions under controlled conditions.
