6-Fluoro-2-(methylthio)-8-nitro-4H-benzo[e][1,3]thiazin-4-one CAS 1383531-43-8

Description

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.

6-Fluoro-2-(methylthio)-8-nitro-4H-benzo[e][1,3]thiazin-4-one (CAS 1383531-43-8) is a high-purity analytical reference standard with the molecular formula C9H5FN2O3S2 and a molecular weight of 272.28 g/mol.

The molecular framework of 6-Fluoro-2-(methylthio)-8-nitro-4H-benzo[e][1,3]thiazin-4-one (C9H5FN2O3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
