(4-(Octyloxy)phenyl)boronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for forming carbon-carbon bonds, making it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group acts as a key intermediate, enabling the coupling of aryl or vinyl halides with arylboronic acids to create complex organic molecules. Additionally, it finds applications in the development of sensors and molecular recognition systems due to its ability to interact with diols and other Lewis bases. Its octyloxy chain enhances solubility in organic solvents, making it suitable for various industrial and research applications.
