“Reagents”: A Pocket Encyclopedia of Reagents for Organic Chemistry

Last updated: May 24th, 2021 |

Reagents is a new app for iPhone and iPad that gives you all the key information about the most commonly encountered reagents in undergraduate organic chemistry courses.

Here’s the key features of Reagents:

  • Profiles of over 80 reagents, along with their key reactions.
  • Examples of each of the representative reactions of each reagent.  There’s hundreds of example reactions in all, from commonplace to obscure.
  • A “Favorites” List – so you can make your own list of only the reagents which are most important to you. You can always modify your list as you progress through the course.

And for a limited time it’s also free.

What does this mean for you?

  • More efficient studying. Spend less time hunting down information: all the key details for every reagent are accessible in seconds.
  • Less time being lost in class. Need a refresher on that reaction?  Forgotten what that reagent does? You can look each reagent up in a snap.
  • Study wherever you go. It’s all on your iPhone – so you can finally cut that umbilical cord between you and your textbook.

My students describe having this problem a lot:

They’re working away on their homework and suddenly need to remind themselves of what a certain reagent (let’s say NaBH4) does. So they have to pull out their 1000 page textbook to look it up. Except… the textbook points them to multiple pages, some of which are relevant, some not. After a minute or two, they get the information they need. Until… five minutes later, when they need to do this again, and again. Hunting through a huge textbook for tiny pieces of information can be a pain. 

What students kept telling me is that they wanted an “abridged textbook” that covered all the reagents in organic chemistry.
To help solve this problem, I developed the Reagent Guide, which puts all the reagents of organic chemistry on your desktop.

Now, in collaboration with Metamolecular, the Reagent Guide has been adapted for the iPhone and iPad.

The result is Reagents –  a pocket encyclopedia of all the most common reagents in organic chemistry. It gives you the comprehensiveness of a textbook, but with all the convenience of a mobile app. 

Now you can answer the question, “What does that reagent do again?” in a few seconds. And then go back to your work.  

In other words, you can spend less time searching for information and more time actually studying. 

Hey, did you see that Reagents is free?
(But act now, because it  won’t be free forever.  This is a limited time offer.) 
UPDATE : Reagents is now available from the App Store for $4.99

  1. Sir please make the app available on playstore/ Android….. Am really looking forward to download the app but can’t just because I don’t use an iPhone

  2. Hello there, I bought your app and was wondering: How much more information is there in your pdf reagent guide? Seeing as it is 5x the price of the app is there 5x more information?

    1. There are extra summary sheets and mechanisms for reactions. It’s also something you can print out and have on your desktop. Regarding price, I think the Reagents app is ridiculously underpriced for what you get.

  3. This is great! However, I am disappointed that this wasn’t broadly publicized (especially when it was free). It does work very well though!

  4. Please make it free again! I’m a broke student who is on the verge of failing org chem because I can’t understand all these reagents and reactions. :(

  5. great looking app. I hope to try it if you release an android version.

    my sense is that there is a larger population of science people and students on the andoid platform than on iphone.

    1. That’s possible – it’s a little harder to develop for due to a larger variety of hardware devices, and also that neither of us have Androids. We’ll let you know when one becomes available.

      1. Lots of interest in an Android version. Funny thing is I use the Reagent Guide primarily on my Android. I have a PDF viewer app. It would be easier to navigate if it were in an actual ‘app’ form, but I don’t have much trouble as it is, it would just be nice to be able to search (which I can’t do on my PDF viewer on my Android).

        Keep up the great work James!!

        1. Thanks for the interest – those who want a droid version have not been shy, and that’s great. I agree in wanting to make search an option for the Reagent guide – the problem is in how it was made in a pretty old-school way (chemdraw to PDF) and a future version should correct that. Not sure it will be soon however.

  6. Dr. Long,
    Can the Regeants App also be downloaded to a laptop?
    Thank you for your response.

    1. No, it’s only for mobile devices. The Reagent Guide has everything that’s in the app, plus mechanisms and more examples, as well as extra summary sheets. It’s available as a downloadable PDF.

  7. Any hope of you possibly acting to create a virtual chemistry model kit like the one you described in one of your previous posts? If so that would be awesome~!!!!!

  8. I like the idea, but I don’t want students using cell phones during class-too much temptation to text and FB etc. Plus will make policing tests even more challenging…

  9. What an incredible app. This is something I dreamed about doing with flash cards, but you’ve done me one better. AND free? I’ll take it.

  10. This is great! Unfortunately I don’t have an iPhone, merely an Android, will there be an Android app as well?

    Thanks in Advance
