Chemical Structure
Description
The occurrence of 4-Chloro-N-(4-fluorobenzylidene)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-N-(4-fluorobenzylidene)aniline (CAS 39769-10-3), molecular formula C13H9ClFN and molecular weight 233.67 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Chloro-N-(4-fluorobenzylidene)aniline (C13H9ClFN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 233.67 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 4-Chloro-N-(4-fluorobenzylidene)aniline 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.
