The occurrence of 1311283-97-2 [1-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylideneaminooxy]-acetic acid ethyl ester MFCD19981253 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.
1311283-97-2 [1-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylideneaminooxy]-acetic acid ethyl ester MFCD19981253 (CAS 1311283-97-2), molecular formula C19H20F3N3O3 and molecular weight 395.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1311283-97-2 [1-[3-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-phenyl]-meth-(E)-ylideneaminooxy]-acetic acid ethyl ester MFCD19981253 (C19H20F3N3O3) 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. 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.
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.
