Chemical Properties Estimation Software System
What is ChemProp?
New Dowload Location
ChemProp can be downloaded for free after signing a license agreement (see below). The download information will be provided by us after receiving the agreement.
Please note, the download information provided in the past will become obsolete soon. From now, ChemProp downloads are located on a new server. At this moment, the old server is still working and contains the access information for the new one. However, it will be stopped in near future.
Of course, anybody holding a license already may alternatively directly contact us to obtain this information. We are very sorry for any inconvenience.
ChemProp License Expiration?
Please note, obsolete ChemProp versions always expire after a certain deadline. Updates will be provided in time, so if your ChemProp installation is expired already, please update from the same source as your original version.
All versions 5.x are expired and removed from the download server already.
Version 6.1 will expire on December 31, 2014.
New versions will be announced by a
Referencing in publications
According to the license agreement, ChemProp must currently be cited as follows:

License agreement download
The ChemProp OSIRIS edition and its successor versions are publicly available for free, based on bilateral license agreements. The license agreement can be downloaded here. It needs to be dated, signed, and stamped by an authorised person.
To simplify ChemProp licensing, licenses will normally not be granted to individual persons (even though this will be possible also), but to entire organisational units. Therefore, an annex to the license agreement defining the organisational unit is required in addition, with the same date, sign, and stamp, as the license agreement. Since the scope of the organisational unit requires our agreement, we strongly recommend to clarify this issue in advance, e.g. via email or phone.
Send both the agreement and the annex together by postal mail to
Helmholtz-Zentrum für Umweltforschung (UFZ)
Department Ökologische Chemie
04318 Leipzig, Germany
Please indicate "ChemProp license agreement" outside of the letter, and provide an email address to receive the access information.
