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 Signals ChemDraw. This version satisfies the needs of all researchers, students and professors involved in chemistry and related fields.

ChemDraw Professional for Mac and Signals ChemDraw 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 functionalities
  • 3D molecule drawings in just a few clicks
  • ChemDraw+: the web application for drawing molecules in the cloud
  • Signals Notebook: the electronic laboratory notebook (ELN)
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:

  • Drawing molecules
  • Calculating stoichiometric data
  • Tool for gel electrophoresis / TLC
  • One-time interfacing with Excel
  • 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:

  • The name = structure function
  • the NMR forecast
  • the ChemFinder database
  • ChemDraw cloud
Customizable HELM & biopolymer toolbar


The cutting-edge tool

Signals ChemDraw is the integrated molecular drawing platform enabling scientists and researchers to capture, store, retrieve, analyze and share data and information on compounds, reactions and properties.

This platform also integrates an electronic laboratory notebook (ELN), accessible via the cloud: Signals Notebook. Specially designed for chemists and biologists, it makes it easy to collect, store and share research work. Encrypted, your data is protected and accessible from any web browser.

Key features of Signals ChemDraw:

  • The Signals Notebook electronic laboratory notebook.
  • The Chemdraw+ application, for drawing molecules in the cloud.
  • ChemDraw Collections, for collecting chemical content (molecules and reactions) on your computer and sorting them by category.
  • HELM Monomer Curation, for easy management of customized monomers.

New ChemDraw 23

The latest version of ChemDraw 23 offers a range of new features, including:

  • Cloud integration with Signals ChemDraw: Signals ChemDraw replaces ChemOffice and integrates all the innovative tools of the ChemDraw suite.
  • ChemDraw+ application: this new cloud-native version of ChemDraw enables you to draw your  molecules directly in the cloud via an intuitive interface.
  • ChemDraw Collections: formerly known as ChemOffice+, this new application lets you better organize, manage, search and share the chemical content (molecules and reactions) on your computer, sorting them by category.
  • HELM Monomer Curation: this application helps you manage and organize your custom monomer libraries, for the construction of biopolymers and complex macromolecules.
