Used as a fluorescent probe in biological imaging due to its strong emission upon binding to proteins or nucleic acids.

Exhibits solvatochromic properties, making it useful in studying microenvironment changes in membranes and macromolecules.

Applied in pH sensing because of its proton-sensitive fluorescence.

Also employed in the development of organic light-emitting diodes (OLEDs) as an electron-transporting material.

Serves as an intermediate in synthesizing pharmaceuticals with antitumor and antimicrobial activities.
