Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as a building block for constructing nitrogen-containing heterocyclic compounds. Its iodo functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the introduction of aromatic or alkenyl groups. This makes it valuable in the development of bioactive molecules, including potential drug candidates and functional materials. The benzyl group can also be modified or removed to fine-tune reactivity or solubility in synthetic pathways.
