Chemical Structure

1-(Carboxymethyl)-5-oxopyrrolidine-3-carboxylic acid CAS 43094-97-9 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 1-(Carboxymethyl)-5-oxopyrrolidine-3-carboxylic acid.

CATO supplies 1-(Carboxymethyl)-5-oxopyrrolidine-3-carboxylic acid (CAS 43094-97-9), a certified reference material (molecular formula C7H9NO5, MW 187.15 g/mol) for analytical method development and quality control.

1-(Carboxymethyl)-5-oxopyrrolidine-3-carboxylic acid (C7H9NO5) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-(Carboxymethyl)-5-oxopyrrolidine-3-carboxylic acid 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.
