(S)-Pyrrolidine-1,2-dicarboxylic acid CAS 54399-67-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-Pyrrolidine-1,2-dicarboxylic acid.

CATO supplies (S)-Pyrrolidine-1,2-dicarboxylic acid (CAS 54399-67-6), a certified reference material (molecular formula C6H9NO4, MW 159.14 g/mol) for analytical method development and quality control.

The molecular framework of (S)-Pyrrolidine-1,2-dicarboxylic acid (C6H9NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
