Description
As a certified reference material (CRM), Lacosamide EP Impurity C (R-isomer) 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.
Lacosamide EP Impurity C (R-isomer) (CAS 2742962-60-1) is a certified pharmaceutical impurity reference standard with the molecular formula C14H20N2O3 and a molecular weight of 264.32 g/mol.
Based on its molecular formula C14H20N2O3, Lacosamide EP Impurity C (R-isomer) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
