Used as a fluorescent probe in biological imaging due to its strong emission properties, enabling visualization of cellular structures and processes. Employed in the synthesis of advanced optical materials, including laser dyes and sensors, because of its efficient light absorption and emission characteristics. Acts as a key intermediate in the preparation of pharmaceuticals and agrochemicals, where its aldehyde functionality allows for further chemical modifications. Also utilized in the development of organic light-emitting diodes (OLEDs) and other photonic devices owing to its favorable photophysical behavior.
