(2-chloro-5-cyclopropylphenyl)boronic acid is primarily used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed in the pharmaceutical industry to create carbon-carbon bonds, enabling the synthesis of complex organic molecules. The compound serves as a key intermediate in the production of various active pharmaceutical ingredients (APIs) and fine chemicals. Its boronic acid group is highly reactive, making it valuable for constructing biaryl structures, which are common in many drugs and organic materials. Additionally, it is utilized in the development of agrochemicals and advanced materials, where precise molecular assembly is required. Its cyclopropyl group adds steric and electronic effects, enhancing its utility in tailored synthetic pathways.
