4-Fluoro-3-methoxyphenylboronic acid（Cat No.:L044678）is an aromatic boronic acid featuring a fluorine atom at the para-position and a methoxy group at the meta-position relative to the boronic acid on the phenyl ring. This compound is widely used in Suzuki-Miyaura cross-coupling reactions for forming carbon–carbon bonds, especially in pharmaceutical and agrochemical synthesis. The electron-withdrawing fluorine and electron-donating methoxy groups create a unique electronic environment that influences reactivity and selectivity. Its structural versatility makes it a valuable intermediate for constructing fluorinated and methoxylated aromatic compounds with potential biological and material science applications.
