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

Since the substance is volatile, clear statements to the biodegradation can be derived only from the Respirometer test . All other tests resulted in statement to the elimination from water. The respirometer test according to OECD guideline 301 F performed by BASF (1981) shows a biodegradion rate of 10 - 30 % after 28 days. This result is supported by a QSAR estimation carried out with CATALOGIC 301 C (v10.14 June,2017). A biodegradation of 2% after 28 is estimated. The prediction is considered as reliable since the the molecule falls into parametric, structural and metabolic domain of the model. The substance is therefore assessed in a weight-of-evidence approach as not readily biodegradable according to OECD criteria.
