2-chloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile; CAS No.: 548797-51-9; 2-Chloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile is a heterocyclic key intermediate, featuring a chlorobenzonitrile and a boronic acid pinacol ester, ideal for Suzuki-Miyaura cross-coupling reactions. As a worldwide chemical supplier, ChemShuttle ensures the global availability of this boronate ester, catering to researchers who need aryl boronic acid equivalents for forming carbon-carbon bonds. The company s small molecules synthesis capabilities allow for the production of this intermediate with high purity, essential for efficient cross-coupling reactions. The chloro group can act as a leaving group, while the boronate ester enables coupling with aryl halides, making it valuable in synthesizing biphenyl or polyaromatic compounds for pharmaceuticals and materials science. ChemShuttle s role as a supplier of boronic acid intermediates supports the widespread use of cross-coupling reactions in modern organic synthesis.
