Software that can be used to make various chemical calculations, such as molecular weight, pH, and redox potentials.

Many people view chemoinformatics as an extension of chemical information, which is a well-established concept covering many areas that employ chemical structures, data storage and computational methods, such as compound registration databases, on-line chemical literature, SAR (Structure-Activity Relationsip) analysis and molecule-property calculation.
