Description of key information

2-methylbut-2-ene has a measured log Kow of 2.67 and therefore is not expected to bioaccumulate. The calculated BCF are 37.1 (TDG equation) and 26.8 (QSAR).

Key value for chemical safety assessment

BCF (aquatic species):
37.1

Additional information

The bioaccumulation in aquatic species study has not been conducted as the substance has a low potential for bioaccumulation (the substance has a log octanol water partition coefficient of less than 3). 2-methylbut-2-ene has a measured log Kow of 2.67 and therefore based on the log Kow, 2-methylbut-2-ene is not expected to bioaccumulate. This is further indicated by the low calculated BCF of 37.1 (TDG part III, p31 QSAR (Veith et al, 1979)) and 26.8 (BCFBAF v3.00, EPISuite 4.00).
