Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing compounds such as pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of the tert-butyloxycarbonyl (Boc) protected aminoethyl group, which is valuable in multi-step syntheses where protection of amine functionalities is required. The iodine atom serves as a good leaving group, enabling further transformations via nucleophilic substitution or cross-coupling reactions. Commonly employed in the development of active pharmaceutical ingredients (APIs) where controlled amine reactivity is needed.
