Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 372.05 g/mol gives Bithionol sulfoxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bithionol sulfoxide (CAS 844-26-8) is a high-purity analytical reference standard with the molecular formula C12H6Cl4O3S and a molecular weight of 372.05 g/mol.
The molecular framework of Bithionol sulfoxide (C12H6Cl4O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures Bithionol sulfoxide 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.
