Used as a key intermediate in the synthesis of anticoagulant drugs, particularly in the development of coumarin-based derivatives with enhanced biological activity. It serves in the preparation of fluorescent probes due to its sulfhydryl group, which allows conjugation with biomolecules for use in bioimaging and sensing applications. Also employed in the design of metal ion sensors, especially for detecting heavy metals in environmental samples, leveraging the thiol group’s strong affinity for metal coordination. Additionally, it finds use in medicinal chemistry for developing novel anti-inflammatory and antimicrobial agents through structural modification at the thiol site.
