Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antitumor and antimicrobial agents. Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in creating complex nitrogen-containing compounds. Commonly employed in organic synthesis to build pyridine-based frameworks, which are prevalent in agrochemicals and bioactive molecules. Also utilized in the preparation of fluorescent probes due to its ability to form conjugated systems useful in imaging and sensing applications.
