Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure allows for selective modifications, making it valuable in constructing complex nitrogen-containing compounds. The iodine moiety serves as a good leaving group, enabling coupling reactions such as cross-couplings or nucleophilic substitutions. It is also employed in the preparation of azetidine-based scaffolds, which are increasingly important in medicinal chemistry due to their favorable metabolic stability and conformational properties. Commonly utilized in research settings for the synthesis of kinase inhibitors, CNS-active agents, and other therapeutic targets.
