What Is SDF/Mol V3000 file format?
✍: Guest
SDF (Structural Data File) V3, also call Mol V3000 file, or Molfile V3,
is the improved version of SDF file format.
SDF V3000 was developed and published by Molecular Design Limited (MDL) and became the the most widely used standard for importing and exporting information on molecules.
Here is an example of SDF V3000 file, Molecule-FYI-001.sd3, of a single molecule:
