Chemical Structure
Description
4-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methylidene}hydrazin-1-yl]benzonitrile (CAS 338420-08-9) is a high-purity analytical reference standard with the molecular formula C14H8ClF3N4 and a molecular weight of 324.69 g/mol.
4-[(E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methylidene}hydrazin-1-yl]benzonitrile (C14H8ClF3N4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
