Chemical Structure
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.
N-(2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)ethyl)-2,2-diphenylacetamide (CAS 921575-61-3), molecular formula C26H22FN3O2 and molecular weight 427.47 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)ethyl)-2,2-diphenylacetamide (C26H22FN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), N-(2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)ethyl)-2,2-diphenylacetamide 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.
