Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Disulfiram is considered as being a not readily biodegradable (58% biodegradation within 60 d) and potentially adsorptive substance (log Koc of 3.9 – 4.1). Based on data from the analogue substance tetramethylthiuram disulfide (CAS No. 137-26-8), rapid primary biodegradation in water/sediment and soil systems is expected, with half-lives below 10 days. Based on this information, the parent substance is not expected to persist in the environment. The mineralization DT50 in soil was < 120 d, based on the available data. Mineralization behavior in sediment and water compartments, in contrast, leaves some doubts regarding persistence, due to either methodological deficiencies or short duration of the available studies. Furthermore, once released into the water, hydrolysis may contribute to the degradation of tetraethylthiuram disulfide. Disulfiram is not expected to be bioaccumulative based on all available data.
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.
