Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Koc
- Value:
- ca. 162 dimensionless
- Remarks on result:
- other: no further details reported
- Type:
- log Koc
- Value:
- ca. 2.21 dimensionless
- Remarks on result:
- other: no further details reported
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The log Koc (Koc) value of 2-chlorobenzonitrile was calculated to be 2.21 (162).
- Executive summary:
The Koc value was estimated using PKOC v1.66. The log Koc (Koc) of 2-chlorobenzonitrile was calculated to be 2.21 (162) (US EPA 2004). Experimental results are not available.
2-chlorobenzonitrile has only a low adsorption potential to soil.
Adsorption to aerosols is not expected. 2-chlorobenzonitrile has a vapour pressure of 6 Pa at 20 °C (see IUCLID section 4.6). With an average load of aerosols in the atmosphere (according to TGD, EU 2003, the specific aerosol surface is 5.6 * 10^-6 cm²/cm³), less than 0.1 % of 2-chlorobenzonitrile is adsorbed to aerosol particles.
