Description
CATO manufactures 2-(2,4-Difluorophenoxy)-5-nitropyridine 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.
CATO supplies 2-(2,4-Difluorophenoxy)-5-nitropyridine (CAS 219865-86-8), a certified reference material (molecular formula C11H6F2N2O3, MW 252.17 g/mol) for analytical method development and quality control.
2-(2,4-Difluorophenoxy)-5-nitropyridine (C11H6F2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. 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.
