The chemical compounds archived in this database are aggregated from several different databases and have been processed with different software packages. For appropriate citation of the data entries please check the PDF description files provided for every entry.
The majority of the aggregated compounds are provided in 2D structure and with implicit hydrogen atoms. We utilized the Open Babel (The Open Source Chemistry Toolbox) software package to add explicit hydrogen atoms and to generate 3D structure of the compounds; please comply with the Open Babel license agreements.
