Methyl (2R)-4,4-difluoropyrrolidine-2-carboxylate CAS 1400688-76-7

Description

Compared with other compounds in its class, the molecular weight of 165.14 g/mol gives Methyl (2R)-4,4-difluoropyrrolidine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl (2R)-4,4-difluoropyrrolidine-2-carboxylate (CAS 1400688-76-7), molecular formula C6H9F2NO2 and molecular weight 165.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl (2R)-4,4-difluoropyrrolidine-2-carboxylate (C6H9F2NO2) 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.

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.
