Chemical Structure
Description
The molecular framework of Orphenadrine D3 Citrate (C18H20D3NOC6H8O7) is characterized by deuterium isotope labeling, a flavonoid core, 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).
Orphenadrine D3 Citrate (CAS 1185011-75-9), molecular formula C18H20D3NOC6H8O7 and molecular weight 464.53 g/mol, is a CATO reference standard with documented purity and traceability.
