Chemical Structure
Description
The occurrence of N-(2,4-difluorophenyl)-1-(p-tolyl)methanimine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(2,4-difluorophenyl)-1-(p-tolyl)methanimine (CAS 134018-66-9), a certified reference material (molecular formula C14H11F2N, MW 231.24 g/mol) for analytical method development and quality control.
N-(2,4-difluorophenyl)-1-(p-tolyl)methanimine (C14H11F2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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), N-(2,4-difluorophenyl)-1-(p-tolyl)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.
