4-Oxo-1-(thiophene-2-sulfonyl)pyrrolidine-2-carboxylic acid CAS 1219300-29-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 275.30 g/mol gives 4-Oxo-1-(thiophene-2-sulfonyl)pyrrolidine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Oxo-1-(thiophene-2-sulfonyl)pyrrolidine-2-carboxylic acid (CAS 1219300-29-4) is a high-purity analytical reference standard with the molecular formula C9H9NO5S2 and a molecular weight of 275.30 g/mol.

The molecular framework of 4-Oxo-1-(thiophene-2-sulfonyl)pyrrolidine-2-carboxylic acid (C9H9NO5S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 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.
