Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing
ELECTROPHORESIS, EarlyView.ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.

Environmental Progress &Sustainable Energy, EarlyView.Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...
