(3-Chloro-2-fluoro-4-methoxyphenyl)boronic acid is a versatile boronic acid derivative widely used in Suzuki-Miyaura cross-coupling reactions, a key method for forming carbon-carbon bonds in organic synthesis. Its distinct substitution pattern—chloro, fluoro, and methoxy groups—enhances reactivity and selectivity, making it valuable for constructing complex aryl and heteroaryl structures. The compound exhibits good stability under typical reaction conditions and offers compatibility with a range of catalysts and substrates. Its high purity and consistent performance make it a reliable reagent for pharmaceutical, agrochemical, and materials science research. Proper handling under inert conditions is recommended to preserve its integrity.
