Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of complex heterocyclic systems found in antipsychotic and anxiolytic drugs. Due to its chlorine substituents and oxazepine core, it participates in cross-coupling reactions and nucleophilic substitutions, enabling the construction of diverse drug candidates. Also employed in research settings for exploring structure-activity relationships in tricyclic compounds.
