Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its reactivity allows for the introduction of amide functionalities and carbon chain extensions in complex molecule assembly. Commonly employed in alkylation reactions due to the presence of the iodine atom, which serves as a good leaving group. Also utilized in the synthesis of heterocyclic compounds and in medicinal chemistry for constructing drug scaffolds. Suitable for use in research settings where selective functionalization is required.
