Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2S,3S)-1-(tert-butoxycarbonyl)-3-methylpyrrolidine-2-carboxylic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO supplies (2S,3S)-1-(tert-butoxycarbonyl)-3-methylpyrrolidine-2-carboxylic acid (CAS 449758-68-3), a certified reference material (molecular formula C11H19NO4, MW 229.27 g/mol) for analytical method development and quality control.
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.
