4-(3-Chlorophenyl)pyridine CAS 5957-92-6

Description

Compared with other compounds in its class, the molecular weight of 189.64 g/mol gives 4-(3-Chlorophenyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3-Chlorophenyl)pyridine (CAS 5957-92-6), molecular formula C11H8ClN and molecular weight 189.64 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(3-Chlorophenyl)pyridine (C11H8ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 189.64 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), 4-(3-Chlorophenyl)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.
