N-[1-[4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylidene]-hydrazinecarboxylic acid tert-butyl ester (CAS 1311283-89-2) is a high-purity analytical reference standard with the molecular formula C20H23F3N4O2 and a molecular weight of 408.42 g/mol.
The molecular framework of N-[1-[4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylidene]-hydrazinecarboxylic acid tert-butyl ester (C20H23F3N4O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-[1-[4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylidene]-hydrazinecarboxylic acid tert-butyl ester 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.
