7-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide CAS 2100839-75-4

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.

CATO supplies 7-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (CAS 2100839-75-4), a certified reference material (molecular formula C8H7FN2O4S, MW 246.22 g/mol) for analytical method development and quality control.

Structurally, 7-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (C8H7FN2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 246.22 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
