Description
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.
(1-(P-tolyl)-1H-pyrazol-4-yl)(2-((3-(trifluoromethyl)benzyl)oxy)phenyl)methanone (CAS 956779-05-8), molecular formula C25H19F3N2O2 and molecular weight 436.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (1-(P-tolyl)-1H-pyrazol-4-yl)(2-((3-(trifluoromethyl)benzyl)oxy)phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (1-(P-tolyl)-1H-pyrazol-4-yl)(2-((3-(trifluoromethyl)benzyl)oxy)phenyl)methanone 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.
