6-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide CAS 2100839-48-1

Description

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.

6-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (CAS 2100839-48-1), molecular formula C8H7FN2O4S and molecular weight 246.22 g/mol, is a CATO reference standard with documented purity and traceability.

6-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. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 6-Fluoro-5-methoxy-2H-benzo[e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
