“I am a patent attorney and chemist who has become quite beholden to ChemDoodle, particularly the newest version (I've been around since Version 5 or 6, but this thing has gone from great for the price to amazing). Thank you and, indeed, great product!”
Dinsmore & Shohl LLP
“What can I say, above and beyond!!!! ... we are actively recommending the product.”
CS Regulatory Ltd
“I think your program is superior to ChemDraw.”
Southern Illinois University Edwardsville
“ChemDoodle has been a godsend this year.”
Holmdel High School
“Being a mac user I couldn't use chemsketch; found chemdoodle and love it, intuitive to use as well!”
University of Nottingham
“ChemDoodle is an amazingly affordable alternative to ChemDraw. For a fraction of the price, I can get the functionality I need to communicate with my colleagues.”
“ChemDoodle really is a lifesaver - no other chemical structure drawing program on the Mac comes even close...”
“Opened my ChemDraw files nicely; intuitive interface. Very smooth operation.”
“I loved the easy-to-use interface; it made drawing molecules and reactions quick and fun!”
California Polytechnic State University, SLO
“This is one of the best chemical drawing programs I have ever used. It is really easy to navigate and create structures. Much better than competitive programs and does not seem bloated and slow.”
Castech Laboratories LLC
“Chemdoodle is very user friendly. I liked the fact that I could draw chem equations easily and without much frustration. Great application.”
South Texas College
- “I really like the intuitive feel, not to mention all of the neat widgets, of this program! I've been on a hunt for new chemical drawing software ever since I left my last institution where we had a ChemDraw site license. I've only played around with this software for a couple of hours, but I can already tell that this program is well on its way to blowing all of the other contenders out of the water. Well done guys!”
“I've been teaching organic chemistry for 22 years, and have seen a lot of chemical drawing programs. This one is exceptional and I will be recommending this one to my students!”
Red Deer College
“The program is brilliant, very useful for showing NMR to my students.”
The Royal Latin School
“Chemdoodle is excellent, amazing and just unbelievably cheaper than Chemdraw ultra. It is very useful I really liked it and I am going to recommend it to everyone.”
University of Tasmania
“Thank you for giving us a great alternative to ChemDraw! I am using ChemDoodle exclusively now.”
“Many thanks for the quick response, and for a feature-rich piece of software that allows us at cash-strapped state schools to make the nice structures we remember from back when we had site licenses for chemdraw. ChemDoodle kicks butt, and I will spread the gospel to my colleagues!”
University of Missouri, Kansas City
- “Wow! ChemDoodle is such a fantastic chemical drawing software package. Easy to use and PACKED with features it is such a bargain compared to the alternatives. The interface is intuitive and the User Guide is easy to read (I especially enjoy it being a searchable pdf). I've recommended this software to colleagues and will continue to do so. The more features I learn how to use the more I like it! Superb job!”
“ChemDoodle is brilliant! w/ the search option, I can draw Taxol and predict its NMR in 30 secs.”
“I am impressed by the beautiful graphics of this software, and the outstanding operability.”
Tokyo University of Science
“I really love your software and so do my students. We also really like the iPhone app - use it a lot in the Organic Lab I teach.”
University of St. Thomas
“I would strongly recommend ChemDoodle. I find it better than ChemDraw or ISISDraw.”
“I am lost without ChemDoodle.”
University at Buffalo
“Just want to say this is a great alternative to Chemdraw.”
University of Leeds
“I love the program and the app. Goodbye ChemDraw...finally!”
“It is impressive. I love it. Many thanks.”
Coatesville VA Medical Center
“Thanks again for making this software available for Linux, you are doing a really good job and the Linux users really appreciate your effort.”
“The MolGrabber widget has already saved my life and the appearance styling features are outstanding for presentations... yeehaw :)”
“Beautiful program, congratulations!”
L'Université de Genève
“I just wanted to say thank you for your excellent customer service and responsiveness. If only all software companies operated this way!”
“ChemDoodle is really great. In fact, I don't miss anything I know from ChemDraw.”
“You really did a very good job with regard to v7. I would especially commend ChemDoodle 3D, which is georgeous, simple for use, great performance, well organized, smoothly working, with a lot features included. The overall picture is breathtaking.”
Lek Pharmaceuticals D.D.
- “My compliments on version 7. Much cleaner and the UI is more intuitive. This makes the features easy to navigate to, but they remain compartmentalized. The glassware drawings has always been a nice feature, and I am happy to see it has been expanded from the version 5 I used to have. I will give a presentation at my next department meeting, as the common mythology is that NOTHING is as good as ChemDraw. I believe this version will push the burden onto ChemDraw supporters to provide evidence as to what amazing feature it has that this package cannot go toe-to-toe with.”
“I started using ChemDraw back in 1990 or 1991 (on an original Macintosh), back when their price was reasonable, and I was beginning to despair of finding a reasonably priced alternative that was as easy to use. I am glad I found ChemDoodle!!”
Naval Academy Preparatory School
- “We like the look and feel to the software and are really happy that we ended up with ChemDoodle and not some other competitor to ChemDraw. The most important part for nearly all of us was, that within 3 minutes we were able to draw molecules the way we wanted them to be drawn! Also as I already told you, we tested a few things and nothing came close to ChemDoodle, as it exceeds ChemDraws capabilities in a lot of areas (Style-settings, responsiveness of the GUI, drawing options, customization).”
“Loving ChemDoodle, and especially the Recover From Image option.”

Industry leading IUPAC naming algorithms
Our algorithms name molecules naturally and accurately, down to the character and formatting. Please see chapter 14 of the user guide for a thorough explanation. If you find any problems, simply contact us with the structure so we can correct it.
The entire history of the IUPAC nomenclature specification is used in our development. The entire periodic table is supported. Both customizable traditional IUPAC names and Attempted Preferred IUPAC Names (PINs) are generated.
Define over 40 options for customizing how traditional names are created, or to switch between various IUPAC rules.
Display IUPAC names for your structures that automatically update as you draw them. You can even display IUPAC locants on your structures to help with descriptions.
Name to Structure
IUPAC names can be parsed into structure representations as well.

Reclaim your chemical data
Read in chemical files from over 30 formats created by other chemistry software. More than just the molecules are recovered, including reactions, spectra, arrows, shapes and more. Thorough support for MDL, SMILES, CDX, CDXML files and more.
ChemDoodle will paste embedded data into 3rd party applications, like a word processor. So, if you paste a ChemDoodle figure into Microsoft® Word, you will later be able to copy that ChemDoodle figure from Microsoft Word and paste back into ChemDoodle for further editing. Supported on Windows, macOS and Linux, but limited to the operating system the figure was embedded on.
Chemical Data Recovery
ChemDoodle can recover chemical data and figures pasted from other chemical software into 3rd party applications, without needing the other chemical program.
Microsoft Office Recovery
If you no longer have access to Microsoft Office or the original operating system the chemical figure was embedded on, ChemDoodle can search your Microsoft Office files and recover the chemical drawings (ChemDoodle and 3rd party) for extraction and further editing.
Chemical Image Recovery
ChemDoodle contains an advanced feature to completely rebuild chemical drawings from images of molecules, with no chemical data provided. The recovered chemical drawings can be used for further editing or analysis. Chemical Image Recovery (CIR) is also known as Optical Structure Recognition (OSR).
