Impurities can find their way into drug substances and pharmaceutical formulations at every step of the drug manufacturing process. For example, the metal catalysts used in the synthesis of certain compounds, which must be removed due to their toxicity. In the final webinar of our four-part API scale-up strategies series, we presented the benefits of […]
