Used as a fluorescent probe in biological imaging due to its strong emission properties and sensitivity to environmental polarity. Commonly applied in the development of sensors for detecting metal ions, especially in aqueous systems. Serves as a building block in organic semiconductors and optoelectronic materials, including OLEDs and fluorescent dyes. Also utilized in the synthesis of agrochemicals and pharmaceuticals where heterocyclic scaffolds enhance bioactivity. Its derivatives are explored in materials science for designing conjugated polymers with tunable electronic properties.
