Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-fluoro-7-aminosulfonylbenzofurazan 4-fluoro-7-sulfamoylbenzofurazan 4-fluoro-7-sulfamoylbenzofurazane 4-fluoro-7-sulfoamoylbenzofurazan 7-Fluorobenzo[c][1,2,5]oxadiazole-4-sulfonamide 7-fluoro-2,1,3-benzoxadiazole-4-sulfonamide 7-fluorobenz-2-oxa-1,3-diazole-4-sulfonamide 7-fluorobenzofurazan-4-sulfonamide 91366-65-3 abd-f (CAS 91366-65-3), molecular formula C6H12FN3O3S and molecular weight 225.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-fluoro-7-aminosulfonylbenzofurazan 4-fluoro-7-sulfamoylbenzofurazan 4-fluoro-7-sulfamoylbenzofurazane 4-fluoro-7-sulfoamoylbenzofurazan 7-Fluorobenzo[c][1,2,5]oxadiazole-4-sulfonamide 7-fluoro-2,1,3-benzoxadiazole-4-sulfonamide 7-fluorobenz-2-oxa-1,3-diazole-4-sulfonamide 7-fluorobenzofurazan-4-sulfonamide 91366-65-3 abd-f (C6H12FN3O3S) is characterized by an amide group, a sulfone group, a carboxylic acid 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. 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.
