Description of key information
Additional information
Data on physical properties of dodcane1 -thiol (CAS 112 -55 -0) were obtained from experimental data, a number of secondary sources and QSARs. 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 processes was documented in the introductions of the sources. 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. Some data has been read across from tert-dodecanethiol. Both of these substances are Aliphatic Thiols characterized by the sulfhydryl (SH) functional group, and similarities between the physico-chemical, environmental fate and ecotoxicity of these substances is apparent.
Review of the collated information indicates that dodecane-1 -thiol has a relative density of lower than water. Dodecane-1-thiol is expected to partition in organic phase based on the log Pow of >6.5 determined experimentally. Dodecane-1-thiol is expected to volatilize rapidly from surface waters based on an estimated Henry's Law constant of 1056000 Pa.m3.mole-1at 20°C.
Physico -chemical properties and structural analysis indicate that dodecane-1-thiol would not be classified as explosive, oxidising or flammable.
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.
