2-Iodopropane is primarily used as an alkylating agent in organic synthesis, where it introduces the isopropyl group into various compounds. It is commonly employed in the preparation of pharmaceuticals, agrochemicals, and other specialty chemicals. In medicinal chemistry, it serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs). Additionally, it is utilized in the production of dyes, fragrances, and polymers. Its reactivity in nucleophilic substitution reactions makes it valuable for creating complex organic molecules in research and industrial applications.
