Chemical Structure
Description
As a certified reference material (CRM), (S)-Methyl 2-(pyrrolidin-2-yl)acetateHCl 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.
(S)-Methyl 2-(pyrrolidin-2-yl)acetateHCl (CAS 259868-83-2), molecular formula C7H13NO2HCl and molecular weight 179.64 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-Methyl 2-(pyrrolidin-2-yl)acetateHCl (C7H13NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
