Chemical Structure
Description
CATO supplies 3-Hydroxy-pyrrolidine-2-carboxylic acid hydrochloride (CAS 1956319-64-4), a certified reference material (molecular formula C5H9NO3HCl, MW 167.59 g/mol) for analytical method development and quality control.
Structurally, 3-Hydroxy-pyrrolidine-2-carboxylic acid hydrochloride (C5H9NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 167.59 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 3-Hydroxy-pyrrolidine-2-carboxylic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
