Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with potential antitumor and antimicrobial properties. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for constructing heterocyclic compounds. It is also employed in the preparation of isoindoline derivatives, which are found in several drug candidates and functional materials. Additionally, it serves as a building block in organic synthesis for creating complex nitrogen-containing rings important in agrochemicals and dyes.
