1-Benzyl-2-(4-methoxyphenyl)-6-oxopiperidine-3-carboxylic acid CAS 937604-06-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Benzyl-2-(4-methoxyphenyl)-6-oxopiperidine-3-carboxylic acid.

1-Benzyl-2-(4-methoxyphenyl)-6-oxopiperidine-3-carboxylic acid (CAS 937604-06-3) is a high-purity analytical reference standard with the molecular formula C20H21NO4 and a molecular weight of 339.39 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1-Benzyl-2-(4-methoxyphenyl)-6-oxopiperidine-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.39 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.
