Cas no 515131-35-8 (5-Carboxy-2-methylphenylboronic acid, pinacol ester)

5-Carboxy-2-methylphenylboronic acid pinacol ester is a boronic acid derivative widely used in Suzuki-Miyaura cross-coupling reactions due to its stability and reactivity. The pinacol ester group enhances shelf life and handling by protecting the boronic acid moiety from protodeboronation. The carboxyl functional group at the 5-position allows for further derivatization, making it a versatile intermediate in pharmaceutical and materials chemistry. Its structural features facilitate controlled coupling reactions while maintaining compatibility with diverse substrates. This compound is particularly valuable in synthesizing complex biaryl structures, where precise functionalization is required. Suitable for use under inert conditions, it offers consistent performance in organoboron-mediated transformations.
