3-Chloro-2-methyl-5-cyanophenylboronic acid pinacol ester

3-Chloro-2-methyl-5-cyanophenylboronic acid pinacol ester, with CAS 2223033-24-5, is a highly functionalized arylboronic acid pinacol ester. This compound serves as a valuable intermediate in synthetic chemistry, particularly for constructing complex organic molecules. The pinacol boronic ester moiety is stable and readily participates in palladium-catalyzed cross-coupling reactions, such as Suzuki-Miyaura coupling, to form new carbon-carbon bonds. The presence of a chlorine atom and a cyano group on the aromatic ring provides additional handles for further chemical transformations, allowing for the introduction of diverse functionalities into target molecules. It is intended for research use only.

• Handle with appropriate personal protective equipment, including gloves, eye protection, and a lab coat. Use in a well-ventilated area or fume hood to avoid inhalation. Avoid contact with skin and eyes. In case of contact, rinse immediately with plenty of water. Store in a cool, dry place, away from incompatible materials. Refer to the Safety Data Sheet (SDS) for comprehensive safety information before use.
