Chemical Structure
Description
5-Bromo-2-thiophenesulfinic acid, sodium salt (CAS 126715-04-6) is a high-purity analytical reference standard with the molecular formula C4H2BrO2S2Na and a molecular weight of 249.07 g/mol.
The molecular framework of 5-Bromo-2-thiophenesulfinic acid, sodium salt (C4H2BrO2S2Na) is characterized by a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
