2-Fluoro-5-(trifluoromethyl)pyridine-3-boronic acid pinacol ester, 97% (CAS 1128269-66-8) is a high-purity analytical reference standard with the molecular formula C12H14BF4NO2 and a molecular weight of 291.05 g/mol.
2-Fluoro-5-(trifluoromethyl)pyridine-3-boronic acid pinacol ester, 97% (C12H14BF4NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Fluoro-5-(trifluoromethyl)pyridine-3-boronic acid pinacol ester, 97% meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
