Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Study not feasible with the substance as such.
The log Pow of acetonitrile (read-across) was determined to be -0.34.

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.34

Additional information

The substance reacts violently while testing. Read across to acetonitrile was conducted. Three independent publications were therefore evaluated. The published log Pow values for acetonitrile are -0.34 (Hansch, C., 1967), -0.54 (Tanii, H.1984) and -0.74 (Rainey, et al 1993). The publication by Hansch, C. was regarded as most reliable as this study is scientifically acceptable and cited in many relevant databases. Therefore the log Pow of -0.34 was chosen as key parameter.
