A molecule sketching block that supports drawing and editing of molecules and reactions. It provides several keyboard shortcuts provide speedy access to the most common editing features and allow easy and fast creation of even large and complex molecules. The editor is able to export molecules in many common formats, including SMILES and Molfile.

Learn the shortcuts:

•
