4-Chloro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile

4-Chloro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile, with CAS 863868-30-8, is a versatile organic building block for research and development. It combines a chlorobenzonitrile moiety with a pinacol boronate ester, making it highly valuable in synthetic chemistry. The boronate ester group is a common nucleophilic partner in Suzuki-Miyaura cross-coupling reactions, allowing for the formation of new carbon-carbon bonds with aryl or vinyl halides. The presence of both a chlorine atom and a nitrile group on the benzene ring provides additional handles for further functionalization or modification, enabling the synthesis of complex molecules. This compound is typically employed as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and advanced materials for research purposes.

• Handle with appropriate personal protective equipment, including gloves, eye protection, and a lab coat. Use in a well-ventilated area or under a 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. Consult the Safety Data Sheet (SDS) for detailed hazard information and safe handling procedures. For research use only.
