Prediction Modules

Predict a number of properties including physicochemical, ADME, toxicity characteristics. View predicted spectra and chemical shifts for structures containing a number of nuclear isotopes including 1H, 13C, 15N, 19F, 31P. Generate systematic nomenclature, including IUPAC and Index names, for a given structural compound, or provide a chemical name to generate a chemical structure.

1Most predictions have a cost of 10 credits per structure-based prediction, while others are free.
2The Advanced Naming prediction module generates systematic names and chemical structures according to guidelines specified by the International Union of Pure and Applied Chemistry (IUPAC), with customized preferences, for compounds containing up to 255 atoms (excluding H).
