7-[(E)-2-[(3-Chlorophenyl)methylidene]hydrazin-1-yl]-2,4-bis(trifluoromethyl)-1,8-naphthyridine (CAS 338962-22-4), molecular formula C17H9ClF6N4 and molecular weight 418.72 g/mol, is a CATO reference standard with documented purity and traceability.
7-[(E)-2-[(3-Chlorophenyl)methylidene]hydrazin-1-yl]-2,4-bis(trifluoromethyl)-1,8-naphthyridine (C17H9ClF6N4) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 7-[(E)-2-[(3-Chlorophenyl)methylidene]hydrazin-1-yl]-2,4-bis(trifluoromethyl)-1,8-naphthyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
