MOL to SDF Converter
MOL and SDF share the same structure block. SDF simply adds a record separator and an optional data field — which is what many databases and pipelines expect.
MOL vs SDF, precisely
An SDF record is a MOL block followed by zero or more data fields and a line containing
$$$$. That is the only structural difference. Converting a MOL file to SDF makes it
acceptable to tools that only read SDF.
When you need it
- Uploading to a compound database that requires SDF
- Handing structures to an ELN or registration system
- Concatenating several molecules into one multi-record file
Note on data fields
This conversion does not invent metadata — the record will have a structure block and a separator, nothing more. Add data fields in your downstream tool if required.
