Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.08 g/mol gives Sodium(4-bromophenyl)methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium(4-bromophenyl)methanesulfonate (CAS 64755-47-1), a certified reference material (molecular formula C7H6BrO3SNa, MW 273.08 g/mol) for analytical method development and quality control.
Owing to a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Sodium(4-bromophenyl)methanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.08 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 Sodium(4-bromophenyl)methanesulfonate 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.
