Chemical Structure
Description
The occurrence of N-(4-Methoxy-3-(2-oxopiperidin-1-yl)phenyl)-2,3-dihydrobenzo[b][1,4]dioxine-6-sulfonamide 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.
N-(4-Methoxy-3-(2-oxopiperidin-1-yl)phenyl)-2,3-dihydrobenzo[b][1,4]dioxine-6-sulfonamide (CAS 941893-71-6) is a high-purity analytical reference standard with the molecular formula C20H22N2O6S and a molecular weight of 418.46 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(4-Methoxy-3-(2-oxopiperidin-1-yl)phenyl)-2,3-dihydrobenzo[b][1,4]dioxine-6-sulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.46 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.
