MOL2 to SMILES Converter

Convert MOL2 content to SMILES. Best for smaller ligand MOL2 blocks.

File Format Explained

MOL2 is a Tripos structure format used in docking and modeling. It can include atom coordinates, atom types, substructure records, bonds, and charge values.

SMILES is a one-line molecular identifier focused on connectivity. Converting MOL2 to SMILES is useful when you need a searchable string for a ligand from a modeling workflow.

MOL2 files can contain atom-type and charge information that SMILES will not preserve. Check stereochemistry and protonation after conversion.
