Description of key information
The auto-flammability of 1,1-dimethylheptanethiol of 212 ± 5˚C at 99.5 kPa has been read across from tert-dodecanethiol.
Key value for chemical safety assessment
Additional information
The auto-flammability of 1,1 -dimethylheptanethiol has been read across from tert-dodecanethiol. Tremain (2010) is a non-GLP compliant auto-flammability study using a heated flask following EC 440/2008 A15 methods. The study is considered reliable and suitable for use for this endpoint.
The self-ignition temperature for 1,1-dimethylheptanethiol (C9 branched) has been read across from a structural analogue, tert-dodecanethiol (C12 branched). These are branched chain aliphatic thiols characterised by a sulfhydryl (SH) functional group. The substances are of a similar size and structure with a single unifying functional group and thus are expected to have similar physico-chemical properties. 1,1-dimethylheptanethiol and tert-dodecanethiol have similar melting points, both <-20°C and similar boiling points, 194°C and 156°C respectively. The self-ignition temperature of tert-dodecanethiol is 212°C based on proprietary data and the self-ignition temperature of 1,1-dimethylheptanethiol is expected to be similar to this value. Therefore following the similarities between the physico-chemical properties of the substances, a self-ignition temperature of 212°C for 1,1-dimethylheptanethiol has been read across from tert-dodecanethiol.
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.
