3-Iodopyridin-2-ol is primarily utilized in organic synthesis as a versatile building block for the preparation of more complex chemical structures. It serves as a key intermediate in the development of pharmaceuticals, particularly in the synthesis of compounds with potential biological activity. The iodine atom in its structure makes it a valuable candidate for cross-coupling reactions, such as Suzuki or Sonogashira reactions, enabling the formation of carbon-carbon bonds. Additionally, it is employed in the creation of heterocyclic compounds, which are often explored for their medicinal properties. Its role in the synthesis of agrochemicals and materials science further highlights its importance in industrial applications.
