Python API Limitations

This is a prerelease version of the Chemaxon Python API, which is not intended for production usage.

Known Limitations

• Only python 3.11, 3.12 and 3.13 are tested and supported.
• The following chemterm functions are tested (for now): atomCount(), atomCount(<atomNumber>), mass(), formula(), ringAtomCount(), fsp3().
  Other chemterm functions might work as well, but their operation has not been examined.
• We only support the following molecule formats (for now): smiles, cxsmiles, smarts, MOL V2000, MOL V3000, mrv, cxon, name.
• Molecule objects are immutable. That means they cannot be modified after initialization. The maximum supported atom count is 800 (heavy atoms and explicit hydrogens together).
