Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners for textiles and paper. Its structure supports conjugation systems that enhance light absorption and emission, making it valuable in developing sensors and probes for bioimaging. Also employed in the preparation of pharmaceuticals targeting central nervous system disorders due to its ability to cross the blood-brain barrier. Shows potential in agrochemicals as a building block for herbicides and fungicides owing to its stability and reactivity.
