Recent Developments in the Field of Air‐Stable Nickel(0) Precatalysts for Cross‐Coupling Reactions

European Journal of Inorganic Chemistry, EarlyView.
The development of bench‐stable Ni(0) sources aims to replace air‐sensitive [Ni(COD)2] (cod = cycloocta‐1,5‐diene) with easy‐to‐handle alternatives. Through a targeted ligand design, using electron‐deficient dienes, carbenes, and fluorophosphines, researchers have achieved air‐ and moisture‐tolerant complexes that show high catalytic activity in cross ...

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.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...
