SMILES to InChI

SMILES (Simplified Molecular Input Line Entry System) and InChI (International Chemical Identifier) are two formats for representing chemical structures. They both identify chemical substances in a compact way and are widely used in cheminformatics.

This tool converts SMILES strings to InChI strings. Enter a SMILES string in the input box and the corresponding InChI string will be displayed below.
