Compared with other compounds in its class, the molecular weight of 384.44 g/mol gives Bariumpentafluorobenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bariumpentafluorobenzenesulfonate (CAS 71735-31-4), a certified reference material (molecular formula C6F5O3SBa, MW 384.44 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Bariumpentafluorobenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Bariumpentafluorobenzenesulfonate 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.
