Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogenated aromatic structure makes it valuable in cross-coupling reactions, such as Suzuki or Ullmann reactions, enabling the construction of complex organic frameworks. It is also employed in radiolabeling studies due to the presence of iodine, facilitating the tracking of molecular pathways in medicinal research. Additionally, it serves as a building block in the preparation of sulfonamide-based drugs, which exhibit antimicrobial, anti-inflammatory, or anticancer activities.
