Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with anti-inflammatory and antimicrobial properties. Its reactive acyl chloride group enables easy attachment to amines or alcohols, making it valuable for constructing amide or ester linkages in drug design. Also employed in the preparation of fluorescent probes and functional materials due to the stability and electronic properties of the oxadiazole ring. Commonly utilized in medicinal chemistry research for building heterocyclic compound libraries.
