2-Cyano-3-fluoro-6-methylphenylboronic acid pinacol ester

2-Cyano-3-fluoro-6-methylphenylboronic acid pinacol ester (CAS 2253959-58-7) is a versatile organoboron compound with the molecular formula C14H17BFNO2 and a molecular weight of 261.10. This compound features a phenyl ring substituted with a cyano group, a fluorine atom, a methyl group, and a pinacol boronic ester moiety. As a functionalized intermediate, it is primarily intended for research and development applications, particularly in organic synthesis. The boronic ester functionality allows for cross-coupling reactions, such as Suzuki-Miyaura coupling, while the cyano and fluoro groups offer additional sites for further chemical modifications or introduce specific electronic properties. Its structure suggests potential utility in the synthesis of complex molecules, including pharmaceuticals, agrochemicals, and materials science research.

• 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 comprehensive safety information before handling.
