Chemical Structure
Description
CATO supplies (2R,3S)-2-Carboxy-3-hydroxypyrrolidin-1-ium 2,2,2-trifluoroacetate (CAS 1818843-17-2), a certified reference material (molecular formula C5H9NO3C2HF3O2, MW 245.15 g/mol) for analytical method development and quality control.
The molecular framework of (2R,3S)-2-Carboxy-3-hydroxypyrrolidin-1-ium 2,2,2-trifluoroacetate (C5H9NO3C2HF3O2) 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.
CATO manufactures (2R,3S)-2-Carboxy-3-hydroxypyrrolidin-1-ium 2,2,2-trifluoroacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
