Authenticity, traceability, counterfeiting: a challenge to the chemist that can be tackled by Nuclear Magnetic Resonance spectrometry

The traceability of a product may be defined as the “ability to trace the history, application or location of manufactured or distributed products”. In this context, counterfeits based on deliberate copying of processes for generic medicines are not straightforward to detect, unless the molecular probe is the active molecule itself. Natural versus synthetic origin of food or cosmetic ingredients is also a concern to the consumer. In this framework, impurity profiling by chromatography is inadequate. Techniques employing stable isotope analyses, in contrast, deal directly with the target molecule by striping down its atomic composition. Such an intimate constitution is unique and characteristic of the different stages of the history of any molecule.
