Want to refresh your memory on named chemical reactions before an exam or a group meeting? Get all the details with ReactionFlash as a great way to learn named reactions, understand their mechanisms and view examples published in peer-reviewed literature.

Designed and developed in consultation with Professor Dr. Erick M. Carreira of ETH Zürich, the app covers over 875 named chemistry reactions. Professor Carreira has helped ensure that we have all the fundamental reactions that should be part of every chemist’s toolkit: from the best-known ones to the ones only Nobel Prize winners remember!

The app is designed like a set of flash cards so it can be used as a learning tool as well as a reference. Each ‘card’ shows the reaction, its mechanism and examples from peer-reviewed, published literature. It also has a quiz mode that lets you test your knowledge.

Linking into Reaxys enables you to find the most recent examples of each reaction, many with experimental details. Reaxys delivers experimental facts from the literature, enabling researchers to find the best synthetic routes and conditions. Find out more at https://www.elsevier.com/solutions/reaxys

Download the app now and see if you know all the named reactions!

- Learn named reactions
- Review and understand mechanisms

What’s New

Version 2.10

ReactionFlash now covers 875 Named Reactions.
Due to this large number of reactions we decided to redesign the storage of the data on your device resulting in a reduction of the app size by 50%.
You now can zoom a Reaction, a Mechanism or the Examples by pinching - the same way as you would do with any photo. The double tap for the zoom continues to be supported.
We also added most of the reactions mentioned by you or your peers.

Science accessible as it should be

App is easy to use and understand, well developed and it is FREE. Its a nifty little study guide in my phone, and it saves me a ton of time in the lab. I like that it includes the mechanisms, examples and quizzes too. Very helpful, thank you for making this!

A suggestion: Hinsberg test for amines 👍🏼

Great compendium of named reactions

Great for people who took organic chemistry 3+ years ago and are now struggling in grad school because they don't remember basic reactions, but don't need to sift through all the basic organic chemistry material either.

Well made, concise, has the mechanism and usage.

For future versions, doesn't need to be geared so much as a flashcard system as opposed to a straight reference.
