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.
1311283-86-9 N'-[1-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)Ph]-meth-(E)-ylidene]-N-Me-hydrazinecarboxylic acid ethyl ester MFCD19981249 (CAS 1311283-86-9), molecular formula C19H21F3N4O2 and molecular weight 394.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H21F3N4O2, 1311283-86-9 N'-[1-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)Ph]-meth-(E)-ylidene]-N-Me-hydrazinecarboxylic acid ethyl ester MFCD19981249 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 394.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
