ChemOffice Or ChemDraw 19.1

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. Browse within ChemDraw across more than 10 M commercially available compounds by structure, or CAS RN with ChemACX Explorer. 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. 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.

What’s New

Enhanced Hotkeys:
Building off 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. A new navigation hotkey allows you to quickly select and jump from one molecule to another.

Aromatic Display Toggle:
Kekule and non-Kekule representations of aromatic circles can be toggled on already drawn molecules, and a specific representation can be set as a preference when importing or pasting chemical data exchange files such as SMILES strings and mol files.

Facilitated Chemical Structure Pasting::
ChemDraw now supports a simpler 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).

HELM Toolbar and Library Management:Following the HELM 2.0 Standard, developed by the Pistoia Alliance for the rapid transfer of biomolecules, we have added a custom editor for creating, editing and sharing complex biomolecules (natural and unnatural amino and nucleic acids). The current HELM toolbar has been redesigned to be more compact and more accessible. HELM Monomer libraries can be managed, curated and shared across multiple users.

ChemDraw / Reaxys integration:
It is now possible to draw a molecule or a reaction in ChemDraw, and initiate a structure search directly into Reaxys. A Reaxys Proxy Option allows you to direct structure searches to a specific instance of Reaxys that you may have within your company or institution. Also, as part of the PerkinElmer / Elsevier partnership, you can choose to use ChemDraw JS as a drawing editor when you use the online Reaxys website (requires an active Reaxys license).

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.

Dynamic Download of Add-ins:
A folder or URL can be specified in the user preferences to provide controlled access to new, custom functionalities within ChemDraw. Add-in JSON files hosted on a remote location are dynamically accessed to deliver custom new capabilities. (ChemOffice Professional).

Chem3D Integrations:
Chem3D Ultra, part of ChemOffice Professional, is now compatible with the latest versions: GAMESS 18, Gaussian 16W and MOPAC 2016 for advanced computational calculations (respective GAMESS, Gaussian, and MOPAC licenses are required).


The complete ChemOffice suite is for MS Windows only.

Macintosh users can get the ChemDraw Professional version which includes the latest and most feature-filled version of ChemDraw for the Macintosh.



Missing Serial Codes

If you cannot see a suitable serial code for a software version you would like, this is because the Perkin Elmer website has forgotten which software you have downloaded.

So just download afresh the software you would like a code for and Perkin Elmer website will email you serial codes and show them in the "my downloads" link.
