Description

Compared with other compounds in its class, the molecular weight of 207.23 g/mol gives 6-Cyclopentyl-2-oxo-1,2-dihydropyridine-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Cyclopentyl-2-oxo-1,2-dihydropyridine-4-carboxylic acid (CAS 1368348-22-4) is a high-purity analytical reference standard with the molecular formula C11H13NO3 and a molecular weight of 207.23 g/mol.

The molecular framework of 6-Cyclopentyl-2-oxo-1,2-dihydropyridine-4-carboxylic acid (C11H13NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).

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.
