Description
CATO supplies 1,1'-[Biphenyl-4,4'-diylbis(methylene)]bis(4,4'-bipyridinium) Bis(hexafluorophosphate) (CAS 134815-78-4), a certified reference material (molecular formula C34H28N4F6P, MW 637.59 g/mol) for analytical method development and quality control.
1,1'-[Biphenyl-4,4'-diylbis(methylene)]bis(4,4'-bipyridinium) Bis(hexafluorophosphate) (C34H28N4F6P) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 1,1'-[Biphenyl-4,4'-diylbis(methylene)]bis(4,4'-bipyridinium) Bis(hexafluorophosphate) 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.
