The impurity profile of production batches of fluorine-containing drugs can be characterised efficiently using 19 F NMR spectroscopy. This yields the number and proportions of impurities in the bulk drug to a level of ~0.1 mole% in a few minutes of NMR experiment time. The approach has been exemplified using a partially purified batch of the steroidal product fluticasone propionate, the...
