3D molecule viewer
Free, no sign-up. A file you open is drawn in your browser and never leaves your device; a name or SMILES is looked up in PubChem for its 3D shape.
Drag to turn, scroll or pinch to zoom.
How to do it
Type a name, a CAS number or a SMILES, or open a 3D file.
Drag to turn the molecule; scroll or pinch to zoom.
Switch between sticks, ball and stick, and space filling.
Where the 3D shape comes from
A drawn structure has no depth, so a 3D view needs coordinates from somewhere. For a name, a CAS number or a SMILES, the viewer uses PubChem’s computed conformer: one low-energy 3D shape PubChem works out for each compound that is not too large or flexible. For a file, it uses the coordinates in the file, as written by a crystal structure, a docking run or a quantum chemistry program.
The viewer is 3Dmol.js. In the Athanor app, every structure you draw has a 3D view of its own, with orbitals and proteins from the PDB and AlphaFold.
