Compared with other compounds in its class, the molecular weight of 386.85 g/mol gives (2Z)-2-[(2-Chloro-6-fluorophenyl)methylidene]-1-azabicyclo[2.2.2]octan-3-yl N-phenylcarbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2Z)-2-[(2-Chloro-6-fluorophenyl)methylidene]-1-azabicyclo[2.2.2]octan-3-yl N-phenylcarbamate (CAS 477858-52-9), molecular formula C21H20ClFN2O2 and molecular weight 386.85 g/mol, is a CATO reference standard with documented purity and traceability.
(2Z)-2-[(2-Chloro-6-fluorophenyl)methylidene]-1-azabicyclo[2.2.2]octan-3-yl N-phenylcarbamate (C21H20ClFN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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).
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), (2Z)-2-[(2-Chloro-6-fluorophenyl)methylidene]-1-azabicyclo[2.2.2]octan-3-yl N-phenylcarbamate 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.
