Chemical Structure

1-(4-Chloro-2-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid CAS 63674-79-3 chemical structure

Description

As a certified reference material (CRM), 1-(4-Chloro-2-methylphenyl)-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.

CATO supplies 1-(4-Chloro-2-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid (CAS 63674-79-3), a certified reference material (molecular formula C12H12ClNO3, MW 253.68 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4-Chloro-2-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid (C12H12ClNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
