Description
(1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(3-chloro-2,4-difluorophenyl)methanimine (CAS 320422-66-0) is a high-purity analytical reference standard with the molecular formula C17H11Cl2F2N3 and a molecular weight of 366.19 g/mol.
(1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(3-chloro-2,4-difluorophenyl)methanimine (C17H11Cl2F2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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 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.
As a certified reference material (CRM), (1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(3-chloro-2,4-difluorophenyl)methanimine 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.
