Elsevier would like to enrich online articles by visualising and providing details of the chemical structures that you define/select as being the main chemical compounds described in your article. For this purpose, mol files can be uploaded when you are uploading your manuscript/table/figure files in the Elsevier Editorial System (EES).
Please use your preferred drawing tool to export mol files for the drawn chemical structures and ensure that they are unique for the given article, complete and do not contain any R-Groups or other variables.
When submitting on line to a journal using EES mol files must be uploaded as supplementary material. You can upload a zip file containing all your manuscript and supplementary files and the system will unpack these and list each item type.
