Chemical Structure
Description
5-[2-Fluoro-4-(trifluoromethyl)benzoyl]-2-[4-(trifluoromethyl)phenyl]pyridine (CAS 900015-46-5) is a high-purity analytical reference standard with the molecular formula C20H10F7NO and a molecular weight of 413.29 g/mol.
5-[2-Fluoro-4-(trifluoromethyl)benzoyl]-2-[4-(trifluoromethyl)phenyl]pyridine (C20H10F7NO) contains a steroid core, 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5-[2-Fluoro-4-(trifluoromethyl)benzoyl]-2-[4-(trifluoromethyl)phenyl]pyridine 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.
