Description
CATO manufactures (E)-1-(2-chlorophenyl)-2-(2-fluorobenzylidene)hydrazine 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.
CATO supplies (E)-1-(2-chlorophenyl)-2-(2-fluorobenzylidene)hydrazine (CAS 385768-26-3), a certified reference material (molecular formula C13H10ClFN2, MW 248.68 g/mol) for analytical method development and quality control.
(E)-1-(2-chlorophenyl)-2-(2-fluorobenzylidene)hydrazine (C13H10ClFN2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
