Description

Compared with other compounds in its class, the molecular weight of 186.59 g/mol gives 426844-51-1 4,4-Difluoro-L-prolinamide hydrochloride MFCD06797014 (S)-4,4-Difluoropyrolidine-2-carboxamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

426844-51-1 4,4-Difluoro-L-prolinamide hydrochloride MFCD06797014 (S)-4,4-Difluoropyrolidine-2-carboxamide hydrochloride (CAS 426844-51-1), molecular formula C5H8F2N2OHCl and molecular weight 186.59 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 426844-51-1 4,4-Difluoro-L-prolinamide hydrochloride MFCD06797014 (S)-4,4-Difluoropyrolidine-2-carboxamide hydrochloride (C5H8F2N2OHCl) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
