Description
CATO manufactures 5-Chloro-2-methylpyridine 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-methylpyridine 1-Oxide (CAS 52313-58-3) is a high-purity analytical reference standard with the molecular formula C6H6ClNO and a molecular weight of 143.57 g/mol.
5-Chloro-2-methylpyridine 1-Oxide (C6H6ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
