1-(4-Fluoro-3-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid CAS 63675-02-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Fluoro-3-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid.

1-(4-Fluoro-3-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid (CAS 63675-02-5), molecular formula C12H12FNO3 and molecular weight 237.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-Fluoro-3-methylphenyl)-5-oxopyrrolidine-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
