2,4,6-Trimethylphenylboronic acid（Cat No.:L017321）, also known as mesitylboronic acid, is an organoboron compound featuring a phenyl ring substituted with three methyl groups at the 2, 4, and 6 positions and a boronic acid functional group. The methyl groups create significant steric hindrance, enhancing the compound’s stability and influencing its reactivity. It is widely used in Suzuki-Miyaura cross-coupling reactions to form carbon–carbon bonds, particularly when bulky or electron-rich aryl groups are desired. Mesitylboronic acid is a valuable reagent in pharmaceutical, agrochemical, and materials chemistry for constructing complex, sterically demanding aromatic structures.
