UUÂãÁÄÖ±²¥

The UUÂãÁÄÖ±²¥ of Chemistry has always been proud of creating high-quality Literature Updating Services that help researchers in the chemical sciences community with their work. However, it has become clear that with the ever-changing needs of the community and advances in chemistry data tools; Analytical Abstracts (AA), Natural Product Updates (NPU) and Synthetic Reaction Updates (SRU) (and its predecessors: Catalysts and Catalysed Reactions (CCR), and Methods in Organic Synthesis (MOS)) were no longer at the forefront of chemistry data searching. As such, we have taken the difficult decision to retire these databases and also the two health and safety databases Chemical Hazards in Industry (CHI) and Laboratory Hazards in Industry (LHB).

In December 2021, AA, NPU and SRU received their last content updates moving to an archive status (CCR, MOS, CHI and LHB have all been static archives since 2018).
