Levetiracetam EP Impurity B, CAS 358629-47-7, corresponds to a defined process- or degradation-related constituent associated with the pyrrolidone-based anticonvulsant scaffold of levetiracetam. With molecular formula C8H12N2O2 and molecular weight 168.19 g/mol, it is a neutral, polar heterocycle whose physicochemical profile supports reversed-phase LC separation but may require orthogonal mass confirmation because of close structural similarity to related analogues. In pharmacopeial and impurity-profile studies, its assignment typically relies on LC-MS/MS, high-resolution LC-MS, and, where necessary, NMR corroboration. Regulatory evaluation focuses on impurity qualification, route-specific origin, and potential accumulation during synthesis or storage.Request a Quote
