2-Chlorophenylboronic acid (Cat No.: R025456) is an organoboron compound featuring a boronic acid functional group attached to a chlorinated phenyl ring at the ortho position. It is widely used in Suzuki–Miyaura cross-coupling reactions for forming carbon–carbon bonds, making it a valuable building block in organic synthesis, pharmaceuticals, and materials science. The ortho-chloro substitution adds electronic and steric effects that can influence reaction selectivity. This compound is essential for constructing biaryl structures, agrochemicals, and active pharmaceutical ingredients with precise functional group arrangements.
