MOL to InChI Converter

Paste a MOL or SDF block and convert it into a standard InChI identifier.

InChI output appears here.

File Format Explained

MOL stores a molecule as atom and bond tables, often with 2D or 3D coordinates. It is useful for editable structure exchange.

InChI is a standardized text identifier generated from the structure. It is useful for search, indexing, registration, and comparing chemical records across databases.

Conversion quality depends on the MOL file having clear atoms, bonds, charges, and stereochemistry. Review the generated InChI for salts, tautomers, and stereochemical layers.
