84806-27-9 7-Fluorobenzo-2-oxa-1,3-diazole-4-sulfonate 4-Benzofurazansulfonic acid, 7-fluoro-, ammonium salt AFSBF Ammonium 4-fluoro-7-sulfobenzofurazan Ammonium-7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonate 7-Fluoro-2,1,3-benzoxadiazole-4-sulfonate 4-Fluoro-7-sulfobenzofurazan SBD-F (CAS 84806-27-9), molecular formula C6H11FN2O4SH3N and molecular weight 243.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 84806-27-9 7-Fluorobenzo-2-oxa-1,3-diazole-4-sulfonate 4-Benzofurazansulfonic acid, 7-fluoro-, ammonium salt AFSBF Ammonium 4-fluoro-7-sulfobenzofurazan Ammonium-7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonate 7-Fluoro-2,1,3-benzoxadiazole-4-sulfonate 4-Fluoro-7-sulfobenzofurazan SBD-F (C6H11FN2O4SH3N) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
