Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapor pressure of dodecane-1-thiol as measured by a balance method was determined to be is 1.2 Pa at 25˚C.
Key value for chemical safety assessment
- Vapour pressure:
- 1.2 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of 1-dodecanethiol has been determined to be 1.2 Pa at 25 °C. The vapour pressure was determined in a GLP-compliant, experimental study (Harlan 2011), using the vapour pressure balance method designed to be compatible with Method A4 Vapour Pressure of Commission regular (EC) No 440/2008 of 30 May 2008. The study is considered reliable and suitable for use for this endpoint.
The IPCS International Chemical Safety Certificate includes a vapor pressure for dodecane-1-thiol of 0.33 kPa at 25˚C. No information on the primary source of these data or the methods used is available. However, this information is taken from an internationally peer-reviewed chemical safety card and can be considered reliable and suitable for use for this endpoint.
The data generated by QSAR give a similar value of 1.14 Pa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
