Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The estimated water solubility of octane-1-thiol is 19.84 mg/l at 25°C according to the WSKOW method and 8.85 according to the WaterNT method.

Key value for chemical safety assessment

Water solubility:
19.84 mg/L
at the temperature of:
25 °C

Additional information

The use of a QSAR to predict the water solubility is an appropriate technique and is suitable for this endpoint. Data in the training set were taken from a variety of sources and standard linear regression was used to fit these to fit water solubility to log Kow, melting point and molecular weight. This will be supported by read across from tert-dodecanethiol when testing is complete.
