Chemical Structure
Description
CATO manufactures 1,1’-Diethyl-[4,4’-bipyridine]-1,1’-Diium Iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1,1’-Diethyl-[4,4’-bipyridine]-1,1’-Diium Iodide (CAS 1983-61-5), a certified reference material (molecular formula C14H18N2I, MW 341.21 g/mol) for analytical method development and quality control.
The molecular framework of 1,1’-Diethyl-[4,4’-bipyridine]-1,1’-Diium Iodide (C14H18N2I) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
