Access Reaxys

Note: Reaxys has been tested using Firefox 3.6 with Java 1.6.11 or higher.  If you experience difficulties with the structure editor, please check your Jajva updates or use IE or Safari.  Please check Reaxys technical requirements for details about tested environments.

With Reaxys you can search Beilstein (Organic), Gmelin (Inorganic and organometallic) and Patent Chemistry databases.  Reaxys' search, analysis, and workflow tools are designed around the needs and common tasks of users, including a synthesis planner to design the optimum synthesis route and multistep reactions to identify precursor reactions underlying synthesis of target compounds. Users can filter search results by key properties, synthesis yield, or other ranking criteria.

• Chemcial Substances
• Susbstance Proterty Data (Chemcial, Physical, Spectra, Application, Eelctrical,...data)
• Chemical Reactions (single or multi-step)

Reaxys differs from CrossFire Commander in:

1. Presentation of content. Reaxys is based on the combined content of the CrossFire Databases. The data are standardized and harmonized. Substance (reaction) data from all three sources are merged into one substance (reaction) record.

2. Interface. The Commander interface was mainly functionality driven (e.g. sort, group), highly-sophisticared, but not really easy to use. The Reaxys interface is task-driven (e.g. define a reaction query, get reaction results, refine on reaction properties and output into PDF), intuitive to use and provides a streamlined look and feel, making searches easier.

3. Functionality. We have been careful to ensure that all the key functionality that our users value in Commander are carried through to Reaxys, but made much easier to use and more visible. In addition we have taken the opportunity to add improved search, analysis and workflow tools that are designed around the needs of users. These include:

• Synthesis planner
• Additional search capabilities (e.g. generate structure query from name)
• Intelligent hit ranking and filtering tools
• Smart results visualization (e.g. tabular display)
• Web-application: no client installation on user PC
• Support of Apple Macintosh and OpenURL

Coverage

The three databases that comprise Reaxys contain:

• Selected core chemistry journals (1771-present) (organic, inorganic, organometallic chemistry)
• Slected organic chemistry patent publications (1803-1980)
• English-language organic chemistry patent publications (WO, US, EP: 1976 - present) from the primary International Patent Class IPC C07 Organic Chemistry, A61K Medicinal Preparations (with C07 as sec.!PC), A01N Biocides, Agrochemicals, C09B Dyes.
