Used in the synthesis of pharmaceutical intermediates, particularly in the development of central nervous system agents and anti-inflammatory drugs. Its structure serves as a key building block in heterocyclic chemistry, enhancing metabolic stability and bioavailability in drug candidates. Commonly employed in the preparation of fluorescent dyes and sensors due to its electron-withdrawing properties and ability to form stable conjugated systems. Also utilized in agrochemicals for crop protection products, where it contributes to improved pest selectivity and environmental persistence.
