• Genotoxic impurities
• Structure elucidation
• Impurity profiling
• Active pharmaceutical ingredient

Impurity profiling is one of the most attractive, active and relevant fields of modern pharmaceutical analysis, which includes the identification, structural elucidation and quantitative determination of impurities and degradation products in bulk drugs and their pharmaceutical formulations. NMR spectroscopy has wide applicability because it provides specific information about bonding and stereochemistry within a molecule, which is particularly important in the structural characterization of genotoxic impurities and degradants often present only in extremely limited quantities. The non-destructive, non-invasive nature of NMR spectroscopy makes it a valuable tool for the characterization of impurities and degradants present at very low levels.
