Used in pharmaceuticals as a key heterocyclic scaffold due to its bioavailability and metabolic stability. Found in drugs with antimicrobial, antiviral, anti-inflammatory, and anticancer properties. Employed in agrochemicals for developing herbicides and pesticides thanks to its strong binding and selectivity. Applied in materials science for creating fluorescent dyes, OLEDs, and optoelectronic devices because of its electron-transporting characteristics. Also used in high-energy materials and liquid crystals for advanced technological applications.
