Chemical Structure
Description
CATO supplies 1-(tert-Butyl) 2-ethyl (2R,3S)-3-hydroxypyrrolidine-1,2-dicarboxylate (CAS 556798-62-0), a certified reference material (molecular formula C12H21NO5, MW 259.30 g/mol) for analytical method development and quality control.
The molecular framework of 1-(tert-Butyl) 2-ethyl (2R,3S)-3-hydroxypyrrolidine-1,2-dicarboxylate (C12H21NO5) is characterized by an amino-acid-derived structure, 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
