See the structure and evidence gaps before claiming a molecular property
Enter a chemical name or SMILES. PubChem resolves the identity and shows a confirmable, editable structure; a restricted backend then calculates RDKit descriptors and makes its remaining evidence gaps explicit.
Confirm the molecular structure
Check the PubChem name, 2D structure, and editable SMILES. RDKit analysis starts only after you confirm.

What this demo does
- 1. Resolve identityA chemical name is looked up directly from the browser through PubChem; a SMILES also receives a PubChem identity record first.
- 2. Confirm structureYou inspect the 2D structure and can edit the SMILES. A name guess is never silently treated as model input.
- 3. Calculate structure featuresThe restricted API uses RDKit to calculate formula, molecular weight, LogP, TPSA, and functional-group flags.
- 4. Show gapsIt does not invent redox potential, solubility, or conductivity. When no source-backed connector is active, the gap is itself a result.
