1-[(tert-Butoxy)carbonyl]-2-ethylpyrrolidine-2-carboxylic acid CAS 1245642-77-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 243.30 g/mol gives 1-[(tert-Butoxy)carbonyl]-2-ethylpyrrolidine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-[(tert-Butoxy)carbonyl]-2-ethylpyrrolidine-2-carboxylic acid (CAS 1245642-77-6), a certified reference material (molecular formula C12H21NO4, MW 243.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H21NO4, 1-[(tert-Butoxy)carbonyl]-2-ethylpyrrolidine-2-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
