Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tert-butyl (2R,4R)-4-fluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-1-carboxylate (CAS 1670273-18-3) is a high-purity analytical reference standard with the molecular formula C16H27F4NO4S and a molecular weight of 405.45 g/mol.
The molecular framework of Tert-butyl (2R,4R)-4-fluoro-2-(3-((4,4,4-trifluorobutyl)sulfonyl)propyl)pyrrolidine-1-carboxylate (C16H27F4NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid 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.
