4-Chlorobenzeneboronic acid(CAT: R042744) is an arylboronic acid featuring a chloro-substituted phenyl ring with the boronic acid group positioned para to the chlorine atom. This compound is widely utilized in Suzuki–Miyaura cross-coupling reactions, enabling the formation of biaryl and aryl-heteroaryl bonds under mild conditions. The para-chloro substituent modulates the electronic properties of the aryl ring, offering enhanced selectivity and functional group compatibility in complex synthetic schemes. It is frequently employed in the synthesis of pharmaceuticals, agrochemicals, and organic electronic materials.
