CATO manufactures 5-Chloro-2-((4-chlorophenyl)thio)pyridine 1-oxide 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.
5-Chloro-2-((4-chlorophenyl)thio)pyridine 1-oxide (CAS 92146-33-3), molecular formula C11H7Cl2NOS and molecular weight 272.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloro-2-((4-chlorophenyl)thio)pyridine 1-oxide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
