Chemical Structure
Description
6-[2-(6-chloro-3-pyridyl)ethynyl]-1H-1,8-naphthyridin-2-one (CAS 2623616-91-9), molecular formula C15H8ClN3O and molecular weight 281.70 g/mol, is a CATO reference standard with documented purity and traceability.
6-[2-(6-chloro-3-pyridyl)ethynyl]-1H-1,8-naphthyridin-2-one (C15H8ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 6-[2-(6-chloro-3-pyridyl)ethynyl]-1H-1,8-naphthyridin-2-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.
