Chemical Properties Estimation Software System
What is ChemProp?
Referencing in publications
According to the license agreement, ChemProp must currently be cited as follows:
UFZ Department of Ecological Chemistry 2019. ChemProp 6.7.1
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.

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. If you do not have the current download access information available, just ask by email again.
All versions up to 6.6 are expired already.
Version 6.7 will be expired after December 31, 2019.
The current version 6.7.1 will be expired after December 31, 2021.
Version 6.7.1 only extends the expiration. It is necessary because 7.0 will not be ready yet within 2019.
The major update to 7.0 is still in preparation. Its release is currently scheduled for the first half of 2020.
How to Obtain a ChemProp License
The ChemProp OSIRIS edition and its successor versions are publicly available for free, based on bilateral license agreements. The license agreement can be downloaded from the link below. 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 in particular cases), 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 to
Dr. R. Kühne
firstname.lastname@example.org; +49 341 235-1507
Prof. Dr. G. Schüürmann
email@example.com; +49 341 235-1262
Six Steps to Your ChemProp License
1. Download these two files
2. Fill in the organisational unit in the annex file
3. Get both files dated, signed, and stamped by an authorised person
4. Provide an email address to receive the access information
5, Indicate "ChemProp license agreement" outside of the letter
6. Send all together by postal mail to
Helmholtz-Zentrum für Umweltforschung - UFZ
Department Ökologische Chemie
04318 Leipzig, Germany
