3,3-Dimethyl 5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-4,6-dioxo-hexahydro-2H-pyrrolo[3,4-d][1,2]oxazole-3,3-dicarboxylate (CAS 303151-74-8), molecular formula C17H16ClF3N4O7 and molecular weight 480.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,3-Dimethyl 5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-4,6-dioxo-hexahydro-2H-pyrrolo[3,4-d][1,2]oxazole-3,3-dicarboxylate (C17H16ClF3N4O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
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.
