Other Features & Limitations

  • Save your search results into a file such as MOL, JPG and PNG it again later for further work.
  • All the thermo-physico-chemical property data can be exported as “ikc” file format for your process simulation software. You don’t need to copy and paste many times. Just a few clicks are enough.
  • Extract the specific molecular descriptor values you want for multiple molecules and save them into a file for further tasks (An input file including the list of your chemicals in mol or sdf format is required). Again, you don’t have to copy and paste each of them. Just a few clicks are enough.
  • We do not claim MOL-Instincts can completely replace the experimentation. Experiments may still be necessary, especially when the data need to be absolutely sure; e.g., the commercial plant application. We recommend using MOL-Instincts for speeding up your tasks when they are delayed due to the lack of the property data and molecular information. We add that whenever possible, experiments should be carried out as a good double check.

  • MOL-Instincts should be one of the best choices when experimental data are unavailable or the experimentation is not feasible, which is frequently the case when the target compound cannot be pure enough due to the separation problems, or it is too toxic or too unstable to perform the experiments.

  • We haven’t developed the estimation technologies for all the properties. For example, the auto-ignition temperature, some solid phase properties, and dissociation constant (pKa) are still under development. They contain other critical factors that we haven’t completely understood yet. The data and information per compound in MOL-Instincts are, however, one of the most complete set compared to other sources available at present.

  • The type of chemical compounds is limited in MOL-Instincts. At present, the maximum number of heavy atoms (other than hydrogen isotopes) per compound is up to about 60, but it is limited mostly to 25 due to the overwhelming calculation time. For a similar reason, the type of atoms is limited to C, H, N, O, S, F, Cl, Br, I, Si, P and As only. In spite of this limitation,

    MOL-Instincts covers almost 75% of chemical compounds currently active in industrial applications. This limitation is mostly just a matter of the computation power, which can be overcome by adding more CPUs. We plan to do that in the near future.
