Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of central nervous system agents. Its structure supports the design of molecules with improved metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for modifying amine-containing drugs to enhance blood-brain barrier penetration. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to the stability and polarity imparted by the oxadiazole ring.
