CATO supplies 1,3-Dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide1,3-dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide (CAS 87743-20-2), a certified reference material (molecular formula C8H6Cl2O2S, MW 237.10 g/mol) for analytical method development and quality control.
1,3-Dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide1,3-dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide (C8H6Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1,3-Dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide1,3-dihydro-5,6-dichlorobenzo(c)thiophene-S,S-dioxide 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.
