5-Acetylfuran-2-boronic acid is primarily used in organic synthesis as a key intermediate for the preparation of complex molecules. It is particularly valuable in Suzuki-Miyaura cross-coupling reactions, where it acts as a boronic acid coupling partner to form carbon-carbon bonds. This makes it essential in the synthesis of pharmaceuticals, agrochemicals, and advanced materials. Its furan ring structure and acetyl group also make it useful in the development of heterocyclic compounds, which are often explored for their biological activity. Additionally, it can be employed in the design of sensors and ligands due to its boronic acid functionality, which can interact with diols and other biomolecules.
