Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 dimethyl sulphide (CAS 75 -18 -3) has been taken from a number of primary and secondary sources. The data in key studies from 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.
Review of the collated information indicates that dimethyl sulphide is soluble with a relative density less than water. Dimethyl sulphide is not expected to accumulate in organic phase based on its Log Pow of 0.84. Dimethyl sulphide is expected to volatilize from surface waters based on the vapour pressure of 53.2kPa at 20°C and an estimated Henry's Law constant of 79.6 Pa.m-3.mole-1at 25°C.
The flash point and boiling point results for dimethyl sulphide indicate that this substance would be classified as Category 2 flammable liquid with the hazard statement "highly flammable liquid and vapour" under GHS.
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.
