Molecule Sketcher

The molecule sketching tool includes basic features of molecular drawing, such as single and double bonds, erasers and translating tools, wedges to display stereochemistry and different elements.

Tool	Description
Single Bond	Click or drag to draw a single Carbon bond, click on existing bonds to make double and triple and crossed bonds.
Multi-node bond	Click and drag to draw an alkane chain of Carbon
Multi-atom rings	Multiple options for carbon ring systems
Above the plane bond	Draws a bond coming out of the plane
Below the plane bond	Draws a bond going into the plane
Charge modifiers	And positive or negative charge modifiers to atom nodes
Common Elements	Most commonly used elements, select your chosen element and paint it onto nodes that have been drawn
Other Elements	For other elements select this tool, then click on the atom node you want to change, from there type in the elemental abbreviation
SMILES editor	This field populates as you draw molecules, you can also type in this field to modify the SMILES string and see the resulting structure in the canvas
File upload	Click to upload a .sd or .smi containing a single compound
Eraser	Deletes nodes and edges of the molecule graph as you click on the structure
Zoom	Select this tool and click and drag on the canvas to change the scale of the structure
Lasso	Click on drag on the canvas to draw around multiple atoms and bonds
Trash	Delete the structure on the canvas
Undo last step	Undo your last step
Beautify structure	Normalize bond lengths and angles, and fit the structure to the canvas.
