Calculator Plugins Licensing

    The earlier licensing system of the Calculator Plugins has been recently modified. You can find information on the new licensing system below.

    The new licensing system

    The new licensing system consists of 6 different licenses. The new licenses and the calculations that they cover are the following:

    • Structural Calculations: Charge, Conformation, Geometry, Hückel, Refractivity, Hydrogen Bond Donor/Acceptor (HBDA), Structural Frameworks calculations

    • Protonation: pKa, Major Microspecies, Isoelectric Point calculations

    • Partitioning: log P, log D, HLB calculations

    • Isomers: Tautomerization, Stereoisomers, Resonance calculations

    • Solubility: Solubility Predictor

    • NMR: NMR Predictor

    {warning} Being a user of the Calculator Plugins

    Plugin pricing is based on the number of users . Notice that unlike other products, users are those who perform predictions OR those who make informed decisions based on the calculated/predicted properties.

    {warning} Calculation Pack and All Plugin license

    The Calculations Pack and All Plugin licenses are not available for purchase anymore.

    Users who have the Calculations Pack licenses and would like to renew them can choose any 3 of the new licenses above.

    Users who have the All Plugin licenses and would like to renew them get all new licenses.

    {info} Free calculations

    Elemental Analysis calculations (e.g. molecular mass) are free and therefore their usage does not require a license in any ChemAxon product where the calculation is available.

    The 2D Topological Surface Area calculation within the Geometry Group is also free. However, other calculations of the Geometry group are not free.

    {info} About the Structural Calculations license

    The Structural Calculations license covers a wide selection of structural calculations grouped together from our earlier set of calculations. Individual calculations can't be purchased separately.

    {info} About the Structural Calculations license

    The Charge Group contains the Charge Distribution, Polarizability and Orbital Electronegativity calculations.

    The Conformer Group contains the Conformers, Molecular Dynamics and Flexible 3D Alignment calculations.

    The Geometry Group contains the Topology Analysis, Geometry, 2D Topological Surface Area, 3D Molecular Surface Area calculations.
