2-Iodopropane is commonly used as an alkylating agent in organic synthesis, where it introduces the isopropyl group into various compounds. It is particularly useful in the preparation of pharmaceuticals and agrochemicals, enabling the creation of complex molecules. Additionally, it serves as a starting material in the production of other iodine-containing compounds. In research, it is employed as a reagent for nucleophilic substitution reactions, facilitating the study of reaction mechanisms. Its role in the synthesis of organic intermediates makes it valuable in industrial and laboratory settings.
