Functional Group Tool

This tool allows functional groups to be used to build a reaction search query.  

A New window must be started when enabling the FG tool on the Toolbar. Functional Group queries cannot contain any other drawn structural fragments.

Note: Functional Group tools are disabled for normal drawing modes. Select the FG Tool from the toolbar. Reaction tools will also be enabled and disabled accordingly.


Click right on a Functional Group in the drawing area to obtain detailed information about the CAS definition of the group.
