The Ecoscale
Fast and transparent evaluation of organic preparations

Overview
The program requires first the quantities/qualities of all reaction components, followed by the work-up procedure. On this basis, it calculates automatically all other parameters (the data are extracted from the ChemExper database) and provides the final Ecoscale.

The Ecoscale web site is based on the following paper:

EcoScale, a semi-quantitative tool to select an organic preparation based on economical and ecological parameters.
