Description
As a certified reference material (CRM), Mono(1,1'-bis(4-cyanophenyl)-[4,4'-bipyridine]-1,1'-diium) monochloride 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.
Mono(1,1'-bis(4-cyanophenyl)-[4,4'-bipyridine]-1,1'-diium) monochloride (CAS 31515-20-5) is a high-purity analytical reference standard with the molecular formula C24H16N4Cl and a molecular weight of 395.87 g/mol.
The molecular framework of Mono(1,1'-bis(4-cyanophenyl)-[4,4'-bipyridine]-1,1'-diium) monochloride (C24H16N4Cl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
