The occurrence of N-(2-Oxo-2-(2-(4-(trifluoromethyl)benzylidene)hydrazineyl)ethyl)-2-phenoxyacetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2-Oxo-2-(2-(4-(trifluoromethyl)benzylidene)hydrazineyl)ethyl)-2-phenoxyacetamide (CAS 391893-73-5) is a high-purity analytical reference standard with the molecular formula C18H16F3N3O3 and a molecular weight of 379.33 g/mol.
N-(2-Oxo-2-(2-(4-(trifluoromethyl)benzylidene)hydrazineyl)ethyl)-2-phenoxyacetamide (C18H16F3N3O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(2-Oxo-2-(2-(4-(trifluoromethyl)benzylidene)hydrazineyl)ethyl)-2-phenoxyacetamide 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.
