ChemDraw & ChemOffice

With ChemDraw, chemistry is in color!

ChemDraw has long since established itself as the benchmark for molecular structure drawing software. In order to provide each user with the right tool for his or her needs, the software now exists in three versions: ChemDraw Prime, ChemDraw Professional and ChemOffice+ Cloud. This version satisfies the needs of all researchers, students and professors involved in chemistry and related fields.

ChemDraw Professional for Mac and ChemOffice+ Cloud now include an electronic lab notebook that can be accessed via the cloud, allowing for easy and unconstrained collaboration.

5 good reasons to use this software

  • The reference for molecular design
  • Three versions with different functionnalities
  • Many innovative tools
  • A 3D application
  • An integrated laboratory notebook

I started using Chemdraw in 1986, I think I was the first one in Europe. It is still a first-class tool, even after more than 30 years. It has followed me up throughout my whole career, in my research and helped me out for sure to be awarded grants in Biochemistry and Information processing (1999).

Why choose the ChemDraw suite?


The essential features

ChemDraw Prime is the version including the essential features. In addition to providing the common elements such as rings, bonds, chains, atoms and functional groups, ChemDraw Prime includes  property calculators, models of chemical equipment and laboratory equipment as well as drawing tools for TLC plate electrophoresis gel.

> ChemDraw Prime features

  1. Drawing molecules
  2. Calculating stoichiometric data
  3. Tool for gel electrophoresis / TLC
  4. One-time interfacing with Excel
  5. ChemDraw ActiveX / Plugin
Improved keyboard shortcuts for quick sketching


The complete tool for chemists and biologists

ChemDraw Professional is the complete tool for chemists and biologists, incorporating a range of smart tools to make researchers’ daily work easier. In addition to the features of ChemDraw Prime, it includes many innovative tools, such as NMR prediction or the name=structure function. It also allows you to query online databases, explore, organize and process structure data with ChemDraw for Excel, standard ChemFinder and ChemScript, and integrates with lab notebooks.

It also Chem3D with a third-party application interface and ChemFinder Ultra. It helps chemists and biologists better visualize their work, gain insight and correlate biological activity with chemical structures.

ChemDraw Professional finally incorporates the ChemDraw Cloud application, which allows you to draw molecules and reactions online, regardless of the computer you are using (even if it does not include the ChemDraw license), and to re-import those molecules and reactions to your desktop version.

> ChemDraw Professional features

  1. The name = structure function
  2. the NMR forecast
  3. the ChemFinder database
  4. ChemDraw cloud
Customizable HELM & biopolymer toolbar


The state-of-the-art tool

Chemdraw Professional is the complete and intelligent molecular drawing suite enabling scientists and researchers to capture, store, retrieve, analyze and share data and information about compounds, reactions and properties.

Chemdraw Professional also incorporates an electronic lab notebook, accessible via the cloud : Signals. This lab notebook will suit chemists and biologists and makes collecting, storing and sharing your work easy. Encrypted, your data is protected and accessible from any web browser.
