Chemical Structure
Description
The occurrence of (R)-3-Methanesulfonyloxy-pyrrolidine-1-carboxylic acid tert-butyl ester is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (R)-3-Methanesulfonyloxy-pyrrolidine-1-carboxylic acid tert-butyl ester (CAS 141699-57-2), a certified reference material (molecular formula C10H19NO5S, MW 265.33 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H19NO5S, (R)-3-Methanesulfonyloxy-pyrrolidine-1-carboxylic acid tert-butyl ester contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 265.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
