5-Oxopiperidine-2-carboxylic acid CAS 789448-80-2

Description

The occurrence of 5-Oxopiperidine-2-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Oxopiperidine-2-carboxylic acid (CAS 789448-80-2), a certified reference material (molecular formula C6H9NO3, MW 143.14 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Oxopiperidine-2-carboxylic acid is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
