Chemical Structure

6-Amino-2,2-difluoro-2H-benzo[b][1,4]oxazin-3(4H)-one CAS 575473-95-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 200.14 g/mol gives 6-Amino-2,2-difluoro-2H-benzo[b][1,4]oxazin-3(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Amino-2,2-difluoro-2H-benzo[b][1,4]oxazin-3(4H)-one (CAS 575473-95-9), molecular formula C8H6F2N2O2 and molecular weight 200.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 6-Amino-2,2-difluoro-2H-benzo[b][1,4]oxazin-3(4H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.14 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.
