This whitepaper combines expert insights and regulatory guidance to recommend best practices for assigning reliable RRFs, focusing on impurity assay accuracy and method robustness.
In this article, we profile nitazenes and cathinones - two fast-emerging New Psychoactive Substances (NPS) whose potency, availability, and shape-shifting properties are a challenge for analytical scientists, researchers, and regulators.
This practical guide explores the formation pathways of small molecule nitrosamines and NDSRIs, identifies key risk factors such as excipients and pH, and outlines emerging control strategies supported by recent product recall case studies.
