Search for the molecules in the ATB database that are the compound you paste (same InChI: element types, connectivity, hydrogens, net charge and stereochemistry). Each match's stored structure is superimposed on yours by an exact atom correspondence and sorted by the heavy-atom RMSD, in Å. Tautomers, protonation states and stereoisomers of your structure are listed separately as related compounds.

All inputs are first passed through Open Babel to ensure formating consistency.
