2-Nitrophenylboronic acid is widely used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals and agrochemicals. It serves as a building block in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds to create complex organic molecules. This compound is also employed in the development of sensors and probes for detecting carbohydrates and other biomolecules due to its ability to form reversible covalent bonds with diols. Additionally, it finds applications in materials science for the functionalization of surfaces and polymers. Its nitro group further allows for modifications and derivatization, making it versatile in research and industrial processes.
