Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 246.13 g/mol gives Bis(2,2,2-trifluoroethyl) sulfite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bis(2,2,2-trifluoroethyl) sulfite (CAS 53749-89-6), a certified reference material (molecular formula C4H4F6O3S, MW 246.13 g/mol) for analytical method development and quality control.
The molecular framework of Bis(2,2,2-trifluoroethyl) sulfite (C4H4F6O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
CATO manufactures Bis(2,2,2-trifluoroethyl) sulfite 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.
