Used primarily in organic synthesis, it serves as a key intermediate in cross-coupling reactions, such as Suzuki-Miyaura reactions, to form carbon-carbon bonds. It is valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. Its ethynyl and boronic acid functional groups enable versatile reactivity, making it useful in constructing complex molecular structures. Additionally, it finds applications in the development of sensors and polymers due to its ability to interact with various organic and inorganic compounds.
