2-(Difluoromethoxy)-5-(2,3-difluorophenyl)pyridine CAS 1261764-07-1

Description

Compared with other compounds in its class, the molecular weight of 257.18 g/mol gives 2-(Difluoromethoxy)-5-(2,3-difluorophenyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Difluoromethoxy)-5-(2,3-difluorophenyl)pyridine (CAS 1261764-07-1), molecular formula C12H7F4NO and molecular weight 257.18 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Difluoromethoxy)-5-(2,3-difluorophenyl)pyridine (C12H7F4NO) 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. 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.

As a certified reference material (CRM), 2-(Difluoromethoxy)-5-(2,3-difluorophenyl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
