Chemical Structure
Description
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.
CATO supplies (2S)-4,4-Difluoro-2-methylpyrrolidine (CAS 1670259-98-9), a certified reference material (molecular formula C5H9F2N, MW 121.13 g/mol) for analytical method development and quality control.
(2S)-4,4-Difluoro-2-methylpyrrolidine (C5H9F2N) contains fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), (2S)-4,4-Difluoro-2-methylpyrrolidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
