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'-Bis(2-ethoxy-2-oxoethyl)-[4,4'-bipyridine]-1,1'-diium bromide (CAS 75539-74-1) is a high-purity analytical reference standard with the molecular formula C18H22N2O4Br and a molecular weight of 410.29 g/mol.
The molecular framework of 1,1'-Bis(2-ethoxy-2-oxoethyl)-[4,4'-bipyridine]-1,1'-diium bromide (C18H22N2O4Br) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1,1'-Bis(2-ethoxy-2-oxoethyl)-[4,4'-bipyridine]-1,1'-diium bromide 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.
