New Version of ChemOffice® Professional 18.1, the Scientifically Intelligent Productivity Suite for Chemists and Biologists.

ChemOffice Professional is the most robust, scientifically-intelligent research productivity suite in the world. It builds on the foundations of ChemDraw Professional, and adds access to a broad set of powerful scientific tools* to enable scientific research. Document, search and share your research using Signals Notebook Individual Edition, a modern, web-based scientific collaboration platform. Load and process 1D NMR and LC/GC/MS data directly on your desktop with MNova ChemDraw Edition. Get access to, and edit, your ChemDraw files from any device with ChemDraw Cloud. Enhanced structural prediction with your favorite third party applications and Chem3D Ultra. Enhanced chemical database management with ChemFinder Ultra. A full suite of scientific productivity tool helping chemists and biologists alike efficiently keep track of their work, visualize and gain a deeper understanding of their results.

ChemOffice® Professional 18.1 Suite Highlights

  • ChemDraw/Reaxys Integration: PerkinElmer and Elsevier have established a partnership to provide you with new and unique ways to improve your Research productivity. It is now possible to draw a molecule or a reaction in ChemDraw, and initiate a structure search into Reaxys. A Proxy Option allows you to direct structure searches to a specific instance of Reaxys that you may have within your company or institution. You can also choose to use ChemDraw JS as a drawing editor when you use the online Reaxys website.
  • ChemACX Explorer: Thanks to the new add-in architecture in ChemDraw, you can now explore chemical properties or supplier information for a given molecule by looking up and retrieving information directly from, PerkinElmer’s database of over 10M commercially available compounds, and quickly paste structures back into the canvas. This feature is also available through Signals Notebook Individual Edition.
  • HELM Editor: Designed to easily create, edit and share complex biomolecules, the HELM toolbar now supports the latest Pistoia Alliance Format, and each monomer entry now displays up to 6 characters of the monomer nickname. Its overall design is more compact to allow for more screen real estate.
  • Shared libraries of HELM monomers: If you are into HELM notation (for peptides, nucleic acids, ADCs etc.) you now have the possibility to connect to different libraries of monomers and manage and curate the content of those libraries. One of the default libraries available (“PerkinElmer”) is the public library from
  • Enhanced Hotkeys: Building off of the powerful hotkeys already enabled within the application, we have enhanced this capability so now you can truly create molecules and reactions as fast as you can type. The Tab key is now available as a new way to select and navigate from one molecule to another.
  • Aromatic Cycle Display Toggle: Easily switch from a localized/delocalized electron display on already drawn molecules. Set as a new preference by default to represent alternating double bonds instead of the delocalized representation when opening of pasting SMILES strings.
  • Facilitated chemical structure pasting: ChemDraw now supports a simplifed, more direct pasting of CDXML and other text formats like SMILES, Mol, InChi, and HELM as a structure using the Edit>Paste (Ctrl+V) menu option, with plain text in the clipboard. You can also copy/paste to and from ChemDraw JS, ChemDraw and MS Office embedded ChemDraw documents without loss of chemical information (requires browser-specific clipboard extension, Windows only).
  • ChemACX Structure from CAS Registry Number: A new function has been added to look up a CAS RN through, PerkinElmer’s database of commercially available compounds and return the corresponding chemical structure.
  • Structure-to-Name and Name-to-Structure improvements: ChemDraw now supports a new atom numbering scheme, where the numbers are derived from their explicit or implicit values in the IUPAC name, as well as the naming of Enhanced Stereochemistry centers. Names including ‘AND’ and ‘OR’ enhanced stereo centers and absolute stereo centers (in any combination) are now supported.
  • ChemDraw Add-ins: ChemDraw add-ins enable third parties to extend the capability of ChemDraw by integrating features easily and quickly using the latest web-based technologies. Add-in JSON files implemented using Javascript/HTML5 can be remotely or locally accessed to dynamically deliver custom new capabilities. A JavaScript API with extensive feature sets is available with the ChemDraw Add-in platform.
  • ChemDraw JS: (Available for ChemOffice Professional Site Subscriptions only) Make your custom web applications ChemDraw Smart! Built on JavaScript and HTML5, ChemDraw JS can be plugged into web browsers and internal applications that need to be chemicalized. Inside its lightweight packages, ChemDraw JS carries the core functionality of the ChemDraw family including customer’s favourite drawing capabilities, advanced Name-to-Structure, Structure-to-Name, Hotkeys/Shortcuts, Templates and Query Tools.
  • Chem3D 3rd party integrations: Chem3D Ultra 18.1 3rd party integrations are now compatible with GAMESS 18, Gaussian 16W and MOPAC 2016 (respective GAMESS, Gaussian and MOPAC licenses are required)
  • MNova ChemDraw Edition: Users of ChemOffice Professional also get access to MNova ChemDraw Edition, the leading scientific application for the processing of 1D NMR and LC/GC/MS data. With MNova ChemDraw Edition you can import raw data files from your favorite instrument and process them from the comfort of your desktop.
  • Signals™ Notebook Individual Edition: Once you’ve done great science, you need a place to record it. Signals Notebook Individual Edition provides a flexible, modern, electronic lab notebook and collaboration platform where you can store your information about your science, describe your findings and share them with your colleagues. With ChemDraw fully integrated into Signals Notebook, and with our new ChemSearch engine you know that you can draw and find your molecules faster than ever.
