N-Dodecylboronic acid is primarily utilized in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. These reactions are pivotal for forming carbon-carbon bonds, enabling the creation of complex organic molecules used in pharmaceuticals, agrochemicals, and materials science. Its long alkyl chain enhances solubility in organic solvents, making it suitable for reactions in non-aqueous environments. Additionally, it serves as a building block in the development of supramolecular structures and sensors, where its boronic acid group can selectively bind to diols and sugars, facilitating applications in glucose sensing and molecular recognition.
