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)
