Description

The occurrence of 2-Hydroxy-5-(3-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Hydroxy-5-(3-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid (CAS 1261924-06-4), molecular formula C16H16N2O5S and molecular weight 348.37 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H16N2O5S, 2-Hydroxy-5-(3-(pyrrolidin-1-ylsulfonyl)phenyl)nicotinic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 348.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
