Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Oxo-2-(phenylamino)ethylidene)-N-phenyloxazolidine-3-carboxamide.
2-(2-Oxo-2-(phenylamino)ethylidene)-N-phenyloxazolidine-3-carboxamide (CAS 14037-24-2), molecular formula C5H9F2N3O2 and molecular weight 181.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Oxo-2-(phenylamino)ethylidene)-N-phenyloxazolidine-3-carboxamide (C5H9F2N3O2) contains an amide group, a carboxylic acid 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.
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), 2-(2-Oxo-2-(phenylamino)ethylidene)-N-phenyloxazolidine-3-carboxamide 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.
