Used as a key intermediate in the synthesis of anticoagulant rodenticides such as coumatetralyl and brodifacoum. Its structure serves as a core scaffold in the development of vitamin K antagonists, which disrupt blood clotting in pests. Also investigated for its potential in organic light-emitting diodes (OLEDs) due to its fluorescent properties. Shows moderate activity in antimicrobial and antioxidant studies, though not widely used in pharmaceuticals. Employed in research settings for building more complex heterocyclic systems in medicinal chemistry.
