This paper describes a software package to estimate physico-chemical a
nd biological parameters for chemical compounds. To date only a few ch
emicals have a full set of data that describes those properties. Missi
ng parameters can, however, be estimated by use of equations from simp
le parameters such as the boiling point, melting point and molecular w
eight. In this paper the application of the software is demonstrated o
n 20 agricultural chemicals, and the parameters found are compared to
a certain extent towards literature values.
