Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong electron-donating amino group and heterocyclic structure. Its derivatives are employed in the development of sensors for metal ions and biological molecules, taking advantage of the compound’s ability to undergo intramolecular charge transfer. Also utilized in agrochemicals as a building block for herbicides and fungicides. Shows potential in pharmaceutical research for designing compounds with antimicrobial and antitumor activities. Commonly applied in material science for creating luminescent polymers and organic semiconductors.
