Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.22 g/mol gives 3-fluoro-2-methyl-5-sulfamoylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-fluoro-2-methyl-5-sulfamoylbenzoic acid (CAS 2044870-83-7), molecular formula C8H8FNO4S and molecular weight 233.22 g/mol, is a CATO reference standard with documented purity and traceability.
3-fluoro-2-methyl-5-sulfamoylbenzoic acid (C8H8FNO4S) 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.
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.
CATO manufactures 3-fluoro-2-methyl-5-sulfamoylbenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
