Chemical Structure
Description
4-[(E)-2-[(3-Chlorophenyl)methylidene]hydrazin-1-yl]quinazoline (C15H11ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-[(E)-2-[(3-Chlorophenyl)methylidene]hydrazin-1-yl]quinazoline (CAS 339025-71-7), molecular formula C15H11ClN4 and molecular weight 282.73 g/mol, is a CATO reference standard with documented purity and traceability.
