Tetradecaneboronic acid is primarily utilized in organic synthesis as a key reagent in cross-coupling reactions, particularly Suzuki-Miyaura coupling. This reaction is widely employed in the pharmaceutical industry for the construction of carbon-carbon bonds, enabling the synthesis of complex organic molecules, including drug candidates. Its long alkyl chain enhances solubility in organic solvents, making it suitable for reactions in non-polar environments. Additionally, it serves as a building block in materials science for the development of boron-containing polymers and coatings, which exhibit unique properties such as thermal stability and chemical resistance. In research, it is also used as a probe or intermediate in the study of boron chemistry and its applications in catalysis and functional materials.
