To find references using a chemical structure, first draw or upload a structure query.

Click the Draw button in the search field to open the structure editor.


Select the preferred structure editor from the menu in the upper-left corner. Using CAS Draw or ChemDoodle, you have the option to import a structure with CAS Draw, ChemDoodle, or ChemDraw or draw a structure query using CAS Draw or ChemDoodle.


The search will retrieve references that include the structure you draw, either as a complete structure or as substructure. You can apply substructure query features to narrow or broaden the search for the substructures embedded in the references matched. When the query is complete, click the OK button.


If needed, you can click Edit Drawing to return to the Structure Editor, or Remove to delete the structure query. Click the magnifying glass to submit the query.
