Name any chemical structure – structure to IUPAC name, and back

Free AI chemical structure editor · no install · no account needed

Naming a structure by hand is slow and error-prone. In MolChart you draw or paste the molecule and ask for the name; the assistant returns the IUPAC name together with the formula and flags any stereocentres.

How to get the IUPAC name of a structure

1. Open the editor and put the structure on the canvas – type its common name, paste a SMILES, or import a MOL file.
2. Ask “what is the IUPAC name?”, or use Analyze → Structure to name.
3. Optionally ask for properties, stereochemistry (R/S, E/Z) or a 3D view.

Examples

• draw ibuprofen and give its IUPAC name
• draw C1CCC(CC1)O and name it
• draw 2-methylpropan-2-ol
• draw (E)-but-2-enoic acid and confirm the E/Z descriptor

Name → structure

The reverse direction works too: type any IUPAC or trivial name and MolChart draws it, then checks the drawing against PubChem so you can be confident the structure matches the name.

Frequently asked questions

How accurate are the names?

Names are generated by a nomenclature engine and checked against PubChem where the compound is known. For unusual or very large structures, treat the name as a draft and check it.

Can it name structures with stereocentres?

Yes. R/S and E/Z descriptors are included when the stereochemistry is drawn (wedge/hash bonds or stereo SMILES).

Can I go from name to structure?

Yes – type the IUPAC or common name, e.g. “draw 2-methylpropan-2-ol”, and it is drawn and verified.

Does it give other properties?

Analyze → Properties reports the molecular formula, molecular weight, exact mass, logP, hydrogen-bond donors/acceptors and more.
