Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(3-Chlorophenyl)-2-(2-methoxyphenoxy)pyridine-3-carbonitrile (CAS 338964-18-4) is a high-purity analytical reference standard with the molecular formula C19H13ClN2O2 and a molecular weight of 336.77 g/mol.
5-(3-Chlorophenyl)-2-(2-methoxyphenoxy)pyridine-3-carbonitrile (C19H13ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 5-(3-Chlorophenyl)-2-(2-methoxyphenoxy)pyridine-3-carbonitrile 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.
