Chemical Structure
Description
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.
(R)-3-(1-((benzyloxy)carbonyl)pyrrolidin-2-yl)propanoic acid (CAS 2271849-99-9), molecular formula C15H19NO4 and molecular weight 277.32 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-3-(1-((benzyloxy)carbonyl)pyrrolidin-2-yl)propanoic acid (C15H19NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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.
