5-Oxo-1-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)pyrrolidine-3-carboxylic acid (CAS 1707386-76-2), molecular formula C10H10F3N3O3 and molecular weight 277.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Oxo-1-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-4-yl)pyrrolidine-3-carboxylic acid (C10H10F3N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
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.
