Chemical Structure
Description
(3,4-Dichlorophenyl)methanesulfonyl fluoride (CAS 1934735-36-0) is a high-purity analytical reference standard with the molecular formula C7H5Cl2FO2S and a molecular weight of 243.08 g/mol.
(3,4-Dichlorophenyl)methanesulfonyl fluoride (C7H5Cl2FO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (3,4-Dichlorophenyl)methanesulfonyl fluoride 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.
