Even in small quantities, pharmaceutical impurities can have serious negative health impacts and influence the behaviour and efficacy of a drug. Organic impurities fall into a number of categories.

Utilization of fluoroform for difluoromethylation in continuous flow: a concise synthesis of α-difluoromethyl-amino acids
Published in Green Chemistry in 2018 C. Oliver Kappe is our tutor on our Flow Chemistry course and this abstract was published in Green Chemistry showing a collaboration with Lonza in making an API in flow. Abstract: Fluoroform (CHF3) can be considered as an ideal reagent for difluoromethylation reactions. However, due to the low reactivity
