2,2'-Bipyridine-4,4'-dicarboxylic Acid Dimethyl Ester 4,4'-Bis(methoxycarbonyl)-2,2'-bipyridine 4,4'-Dimethoxycarbonyl-2,2'-bipyridine 71071-46-0 D4635 Dimethyl 2,2'-Bipyridine-4,4'-dicarboxylate (CAS 71071-46-0) is a high-purity analytical reference standard with the molecular formula C14H24N2O4 and a molecular weight of 284.35 g/mol.
The molecular framework of 2,2'-Bipyridine-4,4'-dicarboxylic Acid Dimethyl Ester 4,4'-Bis(methoxycarbonyl)-2,2'-bipyridine 4,4'-Dimethoxycarbonyl-2,2'-bipyridine 71071-46-0 D4635 Dimethyl 2,2'-Bipyridine-4,4'-dicarboxylate (C14H24N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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.
