SMILES to Structure

SMILES is a language for representing chemical structures as linear strings of characters. As these strings encode the structures of molecules, they are often used as a compact way to represent molecules in databases and when communicating information about molecules in text.

This tool converts SMILES (simplified molecular-input line-entry system) to a 2D structure.

Enter the SMILES string of the molecule in the text box below to generate the structure. You can save the result as an image with the structure depiction.

Examples: aspirin, penguinone, 18-crown-6, citric acid.

Usage notes

The structure can be saved as a PNG image. SVG, PDF, and other vector formats are available through the SMILES to Structure API. Inquire to learn more about pricing and terms.
