Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 376.46 g/mol gives Milnacipran Impurity N13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Milnacipran Impurity N13 (CAS 105310-75-6) is a certified pharmaceutical impurity reference standard with the molecular formula C23H24N2O3 and a molecular weight of 376.46 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Milnacipran Impurity N13 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Milnacipran Impurity N13 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.
