What to do after drawing
- Modify: “add a chlorine para to the hydroxyl”, “make the double bond Z”, “replace OH with NH2”.
- Analyze: IUPAC name, formula, molecular weight, stereocentres, 3D view.
- Export: PNG or SVG for slides and papers, SMILES or MOL for other software.
Frequently asked questions
Where do the structures come from?
From PubChem. MolChart verifies every named compound it draws against the PubChem record.
Can I change them?
Yes – after drawing, tell the assistant what to change: “add a hydroxyl at C4”, “remove the methyl on N7”, “show the enantiomer”.
Can I get the structure as an image?
Export PNG or SVG from the File menu, free, no account needed.
