Reaxys LibGuide: Using Reaxys

A guide for how to get started, search, personalize and take advantage of Reaxys.

How to use Reaxys

Find step-by-step instructions with screenshots for how to get the most out of search, creating alerts and more.

Reaxys Quick search

Simply enter your natural language keywords and/or drawings and click ‘Find’. Suggestions for keywords are displayed to show the possibilities and the state-of-the-art software Marvin JS is built into the interface to make it easy to create structure and reaction drawings. 

Navigate easily between Quick search, Query builder, Results, Synthesis planner and History. 

Reaxys structure and reaction drawings

Reaxys has embedded Marvin JS, a Java-free editor provided by ChemAxon. This tool allows you to create structure and reaction drawings and supports all Reaxys search means.

Reaxys Query Builder

Query Builder enables the construction of complex queries using a streamlined drag-and-drop interface that includes all the essential search input: narrowly defined properties, including spectra, CAS registry numbers, medicinal chemistry terminology, basic indexes and more! Query Builder also supports structure drawing and molecular formula building.

Every query category in Query Builder includes dedicated forms with predefined parameter sets that are easy to edit and fill in. Even complex medicinal chemistry searches can be successfully performed by first-time users thanks to the intuitive step-by-step construction method

Synthesis planner

Synthesis planner enables users to instantly generate multiple, alternative synthesis pathways for compounds of interest based on information published in peer-reviewed literature.

Synthesis Planner includes links to the eMolecules, Biovia ACD and PerkinElmer ChemACX databases to ensure that all the information about the reagents, catalysts and products is available in one place—including the best options for buying compounds for better-informed synthesize-or-purchase decisions.

How Synthesis Planner works

Reaction records in Reaxys are indexed by specific reactions—and different reports of an individual reaction from different original documents appear in one complete reaction record.

This unique structure provides opportunities for the synthetic chemist to answer not just the question, How is the substance made?, but also to answer the more important question: Considering all preparations of the substance and, in turn, all preparations of all the possible intermediates.

Save & export results

Registered Reaxys users can save searches for future sessions, and export experimental and analytical data in various formats and use it in subsequent research workflows—so you can make better decisions faster.
