Chemical Structure
Description
N-(4-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}phenyl)-3-(trifluoromethyl)benzamide (CAS 478262-20-3), molecular formula C24H19ClF6N4O and molecular weight 528.88 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}phenyl)-3-(trifluoromethyl)benzamide (C24H19ClF6N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-(4-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}phenyl)-3-(trifluoromethyl)benzamide 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.
