Octylboronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a key reagent to form carbon-carbon bonds. This makes it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. Its ability to act as a coupling partner with aryl halides enables the creation of complex organic molecules with high precision. Additionally, it is employed in the development of sensors and catalysts due to its unique reactivity and stability. In materials science, it contributes to the synthesis of polymers and liquid crystals, enhancing their functional properties. Its hydrophobic octyl chain also makes it useful in modifying surfaces for specific applications, such as in coatings or adhesives.
