Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive chloromethyl group, which allows for easy alkylation or substitution reactions. Its oxadiazole core contributes to metabolic stability and bioavailability in drug design, making it valuable in developing antimicrobial, anti-inflammatory, and antitumor agents. Also employed in the preparation of fluorescent dyes and optoelectronic materials owing to its electron-withdrawing properties and aromatic character.
