Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive compounds. The Cbz (carbobenzyloxy) group serves as a protecting group for the amine functionality, allowing selective manipulation of other sites, such as the iodine substituent. It acts as a precursor in the synthesis of complex molecules with potential therapeutic applications, owing to the reactivity of the iodine in cross-coupling reactions like Suzuki coupling or Buchwald-Hartwig amination. Its versatility makes it valuable in medicinal chemistry and drug discovery research.
