Additional information

Data obtained from a well documented proprietary report carried out to OECD guidelines so can be considered reliable and suitable for use as the key study for this endpoint. Study was given a reliability of 2 because it was not carried out to GLP. According to the report's owners the substance di-n-butene can be classified as CAS 11071-47-9 (Isooctene).
