Chemical Structure
Description
As a certified reference material (CRM), 1-Benzyl 2-(tert-butyl) (2S,4R)-4-hydroxypyrrolidine-1,2-dicarboxylate 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.
1-Benzyl 2-(tert-butyl) (2S,4R)-4-hydroxypyrrolidine-1,2-dicarboxylate (CAS 72289-52-2), molecular formula C17H23NO5 and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Benzyl 2-(tert-butyl) (2S,4R)-4-hydroxypyrrolidine-1,2-dicarboxylate (C17H23NO5) is characterized by a flavonoid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
