Please be aware that the subscription to SciFinder will be cancelled with effect from 1 October 2020. Please see this List of useful databases page for alternatives.

IMPORTANT - BACKUP YOUR DATA! You may wish to save the results of any searches you have performed on SciFinder; this will need to be done in advance of cancellation. Please see this document (note: use the 'Print' or 'Export' functions only, 'Save' saves results to the SciFinder server, which you will no longer have access to). There is also more detailed guidance in SciFinder Help (accessible from within SciFinder, click on your Account icon): see the 'Working with Search Results' section, which has subsections for Substance, Patent Markush, Reaction, Reference, and Supplier results. There appear to be options for emailing/downloading results to your computer in various formats.
