ChemOffice Professional

What is available?

We have a campus-wide site licence that includes all current students, faculty, and staff at Stanford.  This agreement includes the desktop version of ChemOffice Professional (PC) and ChemDraw Professional (Mac).  Our agreement includes the PerkinElmer Signals Notebook Individual Edition, a cloud-based electronic notebook, and ChemDraw Cloud. ChemDraw can be used for searching SciFinder and Reaxys.  Mnova ChemDraw Edition is also included with ChemOffice Professional but is a "lite" version of the software.  Because we have a site license to the full version of Mnova, we don't recommend using Mnova ChemDraw.  Learn more about what's new.

After installing the software on a personal computer, users do not need to be connected to the network to use it.   The software is also loaded on the cluster computers located in libraries, dorms, and computing clusters.  The current license agreement expires December 30, 2021.
