Chemical Structure
Description
As a certified reference material (CRM), (2s,4r)-4-Hydroxy-1-(mesitylsulfonyl)pyrrolidine-2-carboxylic acid 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.
(2s,4r)-4-Hydroxy-1-(mesitylsulfonyl)pyrrolidine-2-carboxylic acid (CAS 1955482-84-4) is a high-purity analytical reference standard with the molecular formula C14H19NO5S and a molecular weight of 313.37 g/mol.
The molecular framework of (2s,4r)-4-Hydroxy-1-(mesitylsulfonyl)pyrrolidine-2-carboxylic acid (C14H19NO5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
