Chemical MIME Types Supported Locate in Contents

There are many file formats used to store chemical molecular structures.
The plugin supports twenty-seven different chemical MIME types. Internally all chemical structure data are converted into Chemical Markup Language (CML) before display.

In the table below, the current holder of the format is listed. Due to companies being bought by other companies and products being renamed and absorbed by other products the trail of ownership can be difficult to follow. More information about chemical MIME types can be found at The Chemical MIME Home Page.
