InChI to MOL Converter
Got an InChI from a database and need to open it in ChemDraw or Marvin? Convert it to a MOL file with 2D coordinates.
The usual reason
Public databases hand out InChI strings because they are canonical and unambiguous. Structure editors cannot read them. Converting to MOL gives you a file that opens with a sensible 2D layout, so you can edit, annotate or export it further.
What carries over
InChI encodes connectivity and stereochemistry, so the generated MOL will respect chiral centres. Coordinates, however, are generated fresh — the layout will not match whatever the original source used.
Limitation
If you only have an InChIKey, this will not work. An InChIKey is a hash and cannot be turned back into a structure.
