Chemical Structure

1-(3,5-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid CAS 1016509-99-1 chemical structure

Description

The occurrence of 1-(3,5-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(3,5-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (CAS 1016509-99-1), a certified reference material (molecular formula C11H9F2NO3, MW 241.19 g/mol) for analytical method development and quality control.

Structurally, 1-(3,5-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (C11H9F2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 241.19 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(3,5-difluorophenyl)-2-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.
