2-Naphthylboronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a key reagent for forming carbon-carbon bonds. This makes it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. It is also employed in the synthesis of complex organic molecules, including natural products and polymers, due to its stability and reactivity. Additionally, it finds applications in the development of sensors and fluorescent probes, leveraging its ability to interact with specific analytes. Its role in catalysis and material science further highlights its versatility in modern chemical research and industrial processes.
