5-Chloro-2-fluorophenylboronic acid（Cat No.:L025254）is a halogenated arylboronic acid featuring a chlorine atom at the 5-position and a fluorine atom at the 2-position of the phenyl ring. The boronic acid functional group enables its use in Suzuki-Miyaura cross-coupling reactions for forming carbon–carbon bonds, making it a valuable intermediate in organic synthesis. Its dual halogen substitution allows for selective reactivity and further functionalization. This compound is commonly employed in the development of pharmaceuticals, agrochemicals, and materials science, where electron-withdrawing groups enhance stability, reactivity, and tunable electronic properties of the resulting molecules.
