Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Information about transport and distribution in the environment of 1,3,4-Thiadiazolidine-2,5-dithione, reaction product with hydrogen peroxide and tert-nonanethiol (CAS 91648-65-6) is available regarding soil adsorption and the equilibrium concentration of the dissolved substance in air and water. The adsorption coefficient (Koc) was determined as > 4.27 x 10E5 (logKoc > 5.63) using OECD 121 (Fox, 2012). Rocchio (1991) reported further information about the mobility in soil of the target substance: In an experiment conducted in accordance to OECD 106 it was found that the higher organic carbon content in soil, the higher the mobility of the substance.

The Henry´s Law constant was predicted with the QSAR program HENRYWIN v3.20 by Chemservice S.A. (2013). Applying the Bond method, a value of 2.98 E-2 Pa*m³/mol at 25 °C can be reported.

Distribution modelling and other distribution data are not available for 1,3,4-Thiadiazolidine-2,5-dithione, reaction product with hydrogen peroxide and tert-nonanethiol (CAS 91648-65-6) and are not required under REACH.
