Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-Diphenyl-4,4'-bipyridinium Dichloride (CAS 47369-00-6), molecular formula C22H18N2Cl and molecular weight 345.85 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1'-Diphenyl-4,4'-bipyridinium Dichloride (C22H18N2Cl) 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.
As a certified reference material (CRM), 1,1'-Diphenyl-4,4'-bipyridinium Dichloride 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.
