Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Data on physical and chemical properties for tert-dodecanethiol (CAS 25103 -58 -6) have been taken from a number of primary and secondary sources. The data in these secondary sources are based on a critical evaluation of peer-reviewed data and the selected values are considered to be reliable and representative of the property under investigation. Information on the review process was documented in the introduction of the source. The use of Klimisch codes (Klimisch et al. 1997) was extended to these secondary sources and a reliability code of (2) valid with restrictions was assigned when using the authoritative secondary source. Data for some endpoints will be added when testing is complete.
The solubility was determined in a GLP modified OECD 105 using a slow-stir method obtaining a solubility of 3.93 µg/L.
Review of the collated information indicates that tert-dodecanethiol is less dense than water. Tert-dodecanethiol is expected to volatilize from surface waters based on an estimated Henry's Law constant of 19276.2 Pa.m3.mole-1 at 25°C.
The log Kow was estimated at 7.43 using a validated QSAR based on the measure water solubility value.
The properties of tert-dodecanethiol indicate that it would not be classified as explosive, oxidising or flammable under CLP or DSD.
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.
