Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and functional materials. Its structure supports use in creating nitrogen-containing heterocyclic compounds, which are common in bioactive molecules. The compound’s amine functionality allows for further derivatization, making it valuable in drug discovery research. It is also employed in the preparation of fluorescent probes and dyes due to the isoindoline core, which can contribute to light-emitting properties. Additionally, it finds use in polymer chemistry as a building block for specialty monomers with tailored electronic or thermal properties.
