SDF to MOL Converter
An SDF is just a sequence of MOL records with data fields attached. Converting to MOL strips the metadata and gives you individual structures.
Why strip the SDF wrapper?
Many legacy tools and scripts accept only a single-molecule MOL file and choke on the
$$$$ separator and data fields. Converting each record to a plain MOL block makes
the library compatible with those tools.
What you lose
All SDF data fields — compound names, IDs, custom properties — disappear. If those matter, keep the original SDF as the system of record and use the MOL files only for the tool that needs them.
Record order
Records are written in the same order as they appear in the source file, one block per molecule.
