(S)-tert-Butyl 4,4-difluoropyrrolidine-2-carboxylate (CAS 1353053-69-6), molecular formula C9H15F2NO2 and molecular weight 207.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-tert-Butyl 4,4-difluoropyrrolidine-2-carboxylate (C9H15F2NO2) is characterized by an amide 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.
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.
