2-(6-(N,N-diethylsulfamoyl)-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)acetic acid CAS 897776-13-5 chemical structure

Description

The occurrence of 2-(6-(N,N-diethylsulfamoyl)-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, 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-(6-(N,N-diethylsulfamoyl)-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)acetic acid (CAS 897776-13-5) is a high-purity analytical reference standard with the molecular formula C14H18N2O6S and a molecular weight of 342.37 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(6-(N,N-diethylsulfamoyl)-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.37 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.
