Description
As a certified reference material (CRM), 4'-(4-Fluorophenyl)-2,2':6',2''-terpyridine 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.
4'-(4-Fluorophenyl)-2,2':6',2''-terpyridine (CAS 209901-86-0) is a high-purity analytical reference standard with the molecular formula C21H14FN3 and a molecular weight of 327.35 g/mol.
The molecular framework of 4'-(4-Fluorophenyl)-2,2':6',2''-terpyridine (C21H14FN3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
