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Please note, the download information provided in the past is obsolete now. ChemProp downloads are located on a new server. The old server is still working in a read-only manner and contains the access information for the new one. However, it will be stopped in near future.

Important note: The old access is not working on the new server! In particular, you will not be able to login from the address that is mentioned on the login page. To obtain the updated access information, please login to the old server using the old access data, there click on 2fun-old, and download and read the file "IMPORTANT - new link for download.txt".

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 up to 6.1 are expired and removed from the download server already.

The current version 6.2 will expire on December 31, 2015.

New versions will be announced by a

Database references

In addition, the use of some experimental data or datasets extracted from the ChemProp database for publication requires explicit citation or even a separate permission. Furthermore, any data extracted via ChemProp must not be re-published or propagated.

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
Permoserstraße 15
04318 Leipzig, Germany

Please indicate "ChemProp license agreement" outside of the letter, and provide an email address to receive the access information.

Contacts to clarify the scope of the agreement in advance:

Dr. R. Kühne (; +49 341 235-1507)
Prof. Dr. G. Schüürmann (; +49 341 235-1262)
