Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2,4-Difluorophenyl)(5-methylpyridin-2-yl)methanone (CAS 1187170-63-3) is a high-purity analytical reference standard with the molecular formula C13H9F2NO and a molecular weight of 233.21 g/mol.
(2,4-Difluorophenyl)(5-methylpyridin-2-yl)methanone (C13H9F2NO) 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.
As a certified reference material (CRM), (2,4-Difluorophenyl)(5-methylpyridin-2-yl)methanone 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.
