Pyridine, 3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethyl)-

This chemical, with CAS 2223054-08-6, is a highly functionalized pyridine intermediate. It incorporates a fluorine atom and a trifluoromethyl group on the pyridine ring, which can impart specific electronic and steric properties to target molecules. The key feature is the 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) group, a pinacol boronate ester, which is widely utilized in Suzuki-Miyaura cross-coupling reactions. This allows for the facile introduction of the fluorinated pyridine moiety into various chemical structures, making it valuable for the synthesis of novel pharmaceutical candidates, agrochemicals, and advanced materials in research and development settings.

• Handle with appropriate personal protective equipment (PPE) including gloves, eye protection, and a lab coat. Work 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. Do not ingest. Store in a cool, dry place, away from incompatible materials. Consult the Safety Data Sheet (SDS) for detailed safety information and disposal procedures.
