Students are provided with different browsing options to test themselves. ## Key features - Interactive virtual flashcards - Practice synthetic sequences - Display reagents, starting materials, and products - Natural product and pharmaceutical synthesis - Multiple browsing options for testing ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/chemistry-by-design-target-synthesis-database/id451791347/reviews.md ### 5/5 — Very useful app *2018-07-20* This is a great app to look the drug synthesis in hands but the only problem is we need to use this app online. There is no way to use it in offline mode. Could you plz allow us to use this app in offline mode as well? I would appreciate it ### 5/5 — Good Resource *2018-01-12* This is a very good app for anyone looking to find how therapeutics or natural products are synthesized. In research, this can be used to easily learn how a certain drug is synthesized and ways you can easily modify the synthesis to generate a new compound. This is also important for teaching to show student all the different methods of constructing approved therapeutics. Thanks for the hard work! ### 2/5 — Needs a manual/help *2016-01-01* This app has a unique approach to studying o-chem, and I think it has a lot of potential. I especially like its practicing and practical orientation. However, it is not intuitive to use which is a huge drawback. Providing an example usage or a pop-up how-to when it is first opened after installation would go a long way. If it becomes easier to use, I will improve the rating. ### 5/5 — Amazing App *2014-06-18* I’m a chemistry graduate student and I love this app! I use it to quiz myself about organic reactions every day. It would be great if it could be updated for the larger screen of the iPhone 5. I would also love a feature that would allow the user to see which molecules/sequences were recently added! ### 4/5 — Chemistry by Design *2013-08-11* A wonderful app that will help one appreciate the creative challenges over come by innovative routes to challenging synthetic targets An excellent app to help one appreciate and review synthetic transformations applicable to other targets. An improvement would be to include a classification of the synthetic trams formations on the application. Thank you for Sharing your creative efforts the interested public . ### 5/5 — Great synthesis tool!!! *2013-01-24* This is a great app for those looking to learn more about synthesis than in an O Chem class ### 3/5 — So so *2012-08-12* Ok app...isn't 3d so it doesn't show stereoisomerism or anything, plus the buttons overlap and the presentation is pretty poor ### 4/5 — Nice reference *2012-08-10* The quiz GUI would be a pretty useful study/tutoring tool for Organic I and II. I know it would have been when I took them. The history of the molecule is a nice touch too. Nice app! ### 5/5 — I like! *2012-07-30* Nice app, thanks ### 1/5 — Codeine *2012-05-12* Make sure to entice people with a nice bicyclic. ## Frequently asked questions about Chemistry By Design ### What is Chemistry By Design?
