Chemical Structure
Description
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.
1-(Tert-butyl) 2-methyl (2S,4S)-4-(3,4-difluoro-5-hydroxyphenoxy)pyrrolidine-1,2-dicarboxylate (CAS 2442511-27-3) is a high-purity analytical reference standard with the molecular formula C17H21F2NO6 and a molecular weight of 373.35 g/mol.
The molecular framework of 1-(Tert-butyl) 2-methyl (2S,4S)-4-(3,4-difluoro-5-hydroxyphenoxy)pyrrolidine-1,2-dicarboxylate (C17H21F2NO6) is characterized by a flavonoid core, an amide 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. 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).
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.
