Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Oxo-L-proline 2-(Dimethylamino)ethanol.
CATO supplies 5-Oxo-L-proline 2-(Dimethylamino)ethanol (CAS 23513-72-6), a certified reference material (molecular formula C5H7NO3C4H11NO, MW 218.25 g/mol) for analytical method development and quality control.
5-Oxo-L-proline 2-(Dimethylamino)ethanol (C5H7NO3C4H11NO) 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.
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.
