Bromomethylboronic acid, pinacol ester (Cat No.: M034560) is an organoboron compound featuring a bromomethyl group and a boronic acid moiety protected as a pinacol ester. This bifunctional reagent is widely used in organic synthesis, particularly in Suzuki–Miyaura cross-coupling reactions, where the boronate facilitates C–C bond formation. The bromomethyl group allows for further functionalization through nucleophilic substitution or radical reactions. Its stability and reactivity make it a valuable building block in medicinal chemistry, material science, and the synthesis of complex, functionalized molecules.
