Chemical Structure
Description
The occurrence of (R)-Demethylcitalopram Oxalate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-Demethylcitalopram Oxalate (CAS 852172-07-7), molecular formula C19H19FN2OC2H2O4 and molecular weight 400.41 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-Demethylcitalopram Oxalate (C19H19FN2OC2H2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), (R)-Demethylcitalopram Oxalate 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.
