Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 167.59 g/mol gives (S)-Morpholine-2-carboxylic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-Morpholine-2-carboxylic acid hydrochloride (CAS 1439373-55-3), molecular formula C5H9NO3HCl and molecular weight 167.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-Morpholine-2-carboxylic acid hydrochloride (C5H9NO3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (S)-Morpholine-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.
