Chemical Structure
Description
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.
tert-Butyl 3-((S)-2-amino-N-ethylpropanamido)pyrrolidine-1-carboxylate (CAS 1354026-96-2) is a high-purity analytical reference standard with the molecular formula C14H27N3O3 and a molecular weight of 285.38 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, tert-Butyl 3-((S)-2-amino-N-ethylpropanamido)pyrrolidine-1-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.38 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).
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.
