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.

Additional information

For 1-Propanesulfonic acid, 3-mercapto-, monosodium salt (CAS 17636-10-1) the biodegradability can be predicted by the computer program BIOWIN v4.10 (EPIWIN software) of US-EPA (Chemservice S.A., 2011). The program calculates with seven different models, whereby the overall result gives the ready biodegradability prediction, which is in this case "not readily biodegradable". Further prediction can be made using the modelling tool Toxtree (v.2.5.0), which uses the START (Structural Alerts for Reactivity in Toxtree) plug-in. This is a developed rulebase, which estimates the biodegradability potential of a chemical compound based on structural alerts compiled from the Canadian EPA (START2008)
