Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive bromine sites, which allow for easy functionalization through cross-coupling reactions. Its structure supports the development of bioactive molecules, particularly in creating kinase inhibitors and antimicrobial agents. Also employed in material science for designing specialty polymers with enhanced thermal and oxidative stability. Its rigid isoindoline core contributes to electron-accepting properties, making it useful in certain optoelectronic applications.
