Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and anxiolytic drugs. Its structure serves as a building block for more complex heterocyclic compounds that exhibit biological activity. Commonly employed in medicinal chemistry for constructing diazepine-based scaffolds, which are found in certain sedatives and cognitive enhancers. Also utilized in research settings for designing enzyme inhibitors and receptor modulators due to its favorable ring conformation and functional group compatibility.
