Chemical Structure
Description
5-(3,4-Difluorophenyl)pyridin-2(1H)-one (CAS 1111109-62-6), molecular formula C11H7F2NO and molecular weight 207.18 g/mol, is a CATO reference standard with documented purity and traceability.
5-(3,4-Difluorophenyl)pyridin-2(1H)-one (C11H7F2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(3,4-Difluorophenyl)pyridin-2(1H)-one 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.
