2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethyl)benzonitrile

2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethyl)benzonitrile, identified by CAS 1073355-21-1, is an organoboron compound with the molecular formula C14H15BF3NO2 and a molecular weight of 297.08. It incorporates a trifluoromethyl group and a pinacol boronate ester on a benzonitrile scaffold. This structure makes it a valuable functionalized intermediate in various synthetic routes, particularly in cross-coupling reactions like Suzuki-Miyaura coupling, for introducing both a cyano group and a trifluoromethylated aryl moiety. Its pinacol boronate functionality provides a stable and reactive handle for further chemical transformations in research settings.

• Handle with appropriate personal protective equipment (PPE) including gloves, eye protection, and a lab coat. Use in a well-ventilated area or fume hood. Avoid inhalation, ingestion, and skin contact. 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.
