3-Aminocarbonylphenylboronic acid is widely utilized in organic synthesis, particularly as a key intermediate in the preparation of various biologically active compounds. Its boronic acid group makes it valuable in Suzuki-Miyaura cross-coupling reactions, which are essential for constructing complex organic molecules, including pharmaceuticals and agrochemicals. Additionally, it serves as a building block in the development of sensors and probes, especially for detecting sugars and other analytes, due to its ability to form reversible covalent bonds with diols. In medicinal chemistry, it is employed in the design of enzyme inhibitors and drug candidates, particularly those targeting diseases like cancer and diabetes. Its unique structure also makes it useful in material science for creating functionalized polymers and coatings.
