(4-(Decyloxy)phenyl)boronic acid is primarily utilized in organic synthesis and material science due to its boronic acid functional group. It serves as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules, including pharmaceuticals and polymers. Its decyloxy chain enhances solubility in organic solvents, making it suitable for applications in hydrophobic environments. Additionally, it is employed in the development of sensors and diagnostic tools, as boronic acids can selectively bind to diols and sugars, facilitating glucose detection in medical devices. The compound is also explored in the creation of self-assembled monolayers and advanced materials for surface modification.
