Used as a fluorescent probe in biological imaging due to its strong emission properties in hydrophobic environments. It selectively binds to amyloid fibrils and is applied in the detection of protein aggregates associated with neurodegenerative diseases such as Alzheimer's. Also employed in the development of chemosensors for metal ion detection, particularly zinc and aluminum, in environmental and physiological samples. Its photostability and sensitivity make it suitable for use in solid-state sensors and optoelectronic devices. Additionally, it serves as an intermediate in the synthesis of UV stabilizers for polymers and coatings.
