3D Molecule Visualizer

Pick a molecule from the local list or fetch any compound by name, then rotate and zoom its real 3D structure.

  1. Click a molecule below, or type any compound name and hit "Fetch 3D"
  2. Drag to rotate, scroll to zoom — it auto-rotates when idle
  3. Switch between Ball & Stick and Space Filling, and check the Properties/Senses/Uses/Story tabs

3D structures are fetched live from the NCBI PubChem database — a free chemistry tool for students.

Frequently asked questions

Where does the 3D structure data come from?
It's fetched live from PubChem, the NCBI's free chemistry database, so the structures reflect real, published molecular data rather than approximations.
Can I look up any compound, or just the ones listed?
You can type any compound name and click "Fetch 3D" to pull its structure live from PubChem — the listed molecules are just quick shortcuts.
What's the difference between Ball & Stick and Space Filling?
Ball & Stick shows atoms as small spheres connected by bond sticks, making bond angles and structure easy to read. Space Filling shows atoms at their true relative sizes, packed together as the molecule actually occupies space.
Do I need a chemistry background to use this?
No — it includes plain-language Properties, Senses, Uses and Story tabs for each molecule, so it works well for students exploring chemistry casually too.
Do I need to install anything or sign up?
No. It runs entirely in your browser — no software install, no account, no email required.
