Use this chemical structure search tool to search our chemical database for an exact or substructure match on your molecule of interest. Simply draw a structure fragment or structure in the JME Molecular Editor and click the «Substructure Search» or «Exact Search» button.
First steps:
Click the chemical template of your choice and click in the drawing. The selected structure appears.
Complexe structures:
To attach another template select a carbon structure from the main menu. Click on the atom in the drawing where you want to attach it.
Changing bonds:
In the main menu, select the bond of your choice. Click the bond on the drawing you want to change.
Changing atoms:
To change an atom, click in the left menu the selected atom. Click on the atom in the drawing you want to change. To draw a non standard atom, click on X in the left menu. A window will open. Enter the atom of your choice.
You can block substituents at a particular position by drawing explicit hydrogen atoms. You must add a bond and then add a hydrogen using the X atom function (symbol H). Click on the 'X', a window will open. In this window you can also enter other atoms i.e. Si, Na, Se, etc.
