Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized polymers. Its bromo and phthalimide groups allow for sequential substitution and protection reactions, making it valuable in multi-step syntheses. Commonly employed in the development of bioactive molecules, including kinase inhibitors and labeled compounds for medicinal chemistry research. Also utilized in material science for introducing reactive handles onto surfaces or macromolecules through ether linkage formation.
