Compared with other compounds in its class, the molecular weight of 149.19 g/mol gives Lacosamide EP Impurity G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lacosamide EP Impurity G (CAS 588-46-5) is a certified pharmaceutical impurity reference standard with the molecular formula C9H11NO and a molecular weight of 149.19 g/mol.
The molecular framework of Lacosamide EP Impurity G (C9H11NO) 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 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.
CATO manufactures Lacosamide EP Impurity G under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
