Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3,5,6-Tetrachloro-4-(methylsulfonyl)pyridine (CAS 13108-52-6), molecular formula C6H3Cl4NO2S and molecular weight 294.97 g/mol, is a CATO reference standard with documented purity and traceability.
2,3,5,6-Tetrachloro-4-(methylsulfonyl)pyridine (C6H3Cl4NO2S) contains an amide group, 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 2,3,5,6-Tetrachloro-4-(methylsulfonyl)pyridine 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.
