MDL MolFile (*.mol)

---

MDL Information Systems, Inc. MolFile (MDL MolFile) file format is used by several other Windows, Macintosh, and UNIX chemical databases and drawing applications such as ISIS/Draw, ISIS/Base, MACCS, and REACCS.

ChemDraw Pro provides two MDL MolFile formats:

• MDL MolFile (Text)
• MDL MolFile (Mac) for Macintosh only. This file type is saved with an mMol file type and can be saved and opened with ISIS.

MDL MolFile files are ASCII text files that can be created or edited in common word processing applications or text editors. Atom and bond property information is stored in the MolFile.

MDL RGFile (*.rgf) file format is used by several other chemical databases and drawing applications. The MDL File RGFile supports alternate groups whereas an MDL Molfile cannot. When you save a ChemDraw file that contains alternate groups as an MDL MolFile, it is automatically saved as an MDL RGFile.
