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.
1-Pyrrolidinecarboxylic acid, 4-hydroxy-2-(1-oxopropyl)-, 1,1-dimethylethyl ester, (2R,4R)- (CAS 1932492-10-8), molecular formula C12H21NO4 and molecular weight 243.30 g/mol, is a CATO reference standard with documented purity and traceability.
1-Pyrrolidinecarboxylic acid, 4-hydroxy-2-(1-oxopropyl)-, 1,1-dimethylethyl ester, (2R,4R)- (C12H21NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
