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 1'000 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

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 👍🏼

So informative and handy

ReactionFlash is a very informative application. It is a very handy source of name reactions. I have been entertaining myself doing the quizzes during the nights with a beer in hand.

Please fix the landscape swiping

You can’t swipe through reactions in landscape mode without them shifting partially off screen and requiring an app reset to fix the issue. If this were fixed, the app would be super intuitive and helpful!

Hope it gets fixed!
