Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Estimation of adsorption coefficient on the basis of an approved QSAR model, estimated by the Log Kow Regression method from an experimentally-determined value for octanol-water partition coefficient. 

Key value for chemical safety assessment

Koc at 20 °C:
59.91

Additional information

The Koc for 4-dimethylaminopyridine was estimated to be 59.91 L/kg by QSAR modelling (Kow Regression method); this value was adopted as the key value, since it was based on an experimentally-determined partition coefficient. The estimate based on Molecular Connectivity Index was reported at a similar value of 38.7 L/kg.
