New Electronic Resource: Reaxys

Dr. Jochen Bihn & Laura Tobler, 01. December 2011 |

Lib4RI has licensed Reaxys, a web-based chemistry database that integrates reaction and substance data search with synthesis planning. Search capabilities include searching by reaction, substance, or numeric property data. Substance searching includes (sub-) structure, generic and R-group searching, molecular formula, name and many more choices.
We recommend Reaxys for obtaining the physico-chemical data as well as data on preparation/reaction methods for compounds, and especially for its very good coverage of pre-1960 literature.

The core sources are Beilstein‘s «Handbuch der organischen Chemie» (up to 1959) und Gmelin‘s «Handbuch der Anorganischen Chemie» (up to 1975). These two comprehensive handbooks cover most of the older literature, with references going back to the 18th century. More recent content has been extracted from selected chemical journals. Additionally, Reaxys offers access to the Patent Chemistry Database, which covers English-language patents in the life sciences and chemistry since 1976.
