Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of anticonvulsant and antimicrobial agents. Its structure supports the design of bioactive molecules due to the presence of multiple nitrogen atoms and a sulfur-containing heterocycle, which enhance binding to biological targets. Employed in research for fluorescent probes and sensors because of its electron-rich framework, enabling detection of metal ions or biomolecules. Also explored in materials science for creating conductive polymers and optoelectronic materials owing to its conjugated system and thermal stability.
