Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Diethyl sulphide is considered not to be readily biodegradable based on data read across from methyl ethyl sulphide. This conservative result has been read across as both of these substances are sulphides characterised by a sulphur atom in a carbon chain with the same structure over very similar carbon chain lengths (diethyl sulphide: C4H10S and methyl ethyl sulphide: C3H8S). Given that the substances have the same structure and vary only by a single carbon number, the substances are expected to have similar behaviours in the environment.
Gancet (2011) is a GLP-compliant, ready biodegradation test, performed with ethyl methyl sulphide according to the OECD testing guideline 301D (closed-bottle test), which showed 41% degradation after 28 days. This is supported by Thiébaud (1999), a ready biodegradation test performed with methyl ethyl sulfide according to the OECD testing guideline 301D (closed-bottle test), showing 34% degradation after 28 days. According to these results, methyl ethyl sulphide, and thus diethyl sulphide, is considered as not readily biodegradable.
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.
