Description

Compared with other compounds in its class, the molecular weight of 267.27 g/mol gives 2,3-Bis(4-fluorophenyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3-Bis(4-fluorophenyl)pyridine (CAS 1214365-49-7), molecular formula C17H11F2N and molecular weight 267.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,3-Bis(4-fluorophenyl)pyridine (C17H11F2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 267.27 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.

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), 2,3-Bis(4-fluorophenyl)pyridine 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.
