N-(4-Fluorobenzylidene)aniline CAS 5676-81-3

Description

The occurrence of N-(4-Fluorobenzylidene)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(4-Fluorobenzylidene)aniline (CAS 5676-81-3), molecular formula C13H10FN and molecular weight 199.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(4-Fluorobenzylidene)aniline (C13H10FN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 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.
