Additional information

Although 2 -chlorobutane itself is not readily biodegradable as shown in an OECD301D-test, the substance is considered to be rapidly degradable under environmentally relevant conditions. The hydrolysis study showed that 2 -chlorobutane degrades in the environmentally relevant pH range of 5 - 9 (actually ph 4 - 9 was measured) at 27 °C within a half-life time of 55 - 65 hours. The hydrolysis product is 2 -butanol which has been shown to be readily biodegradable.

In addition 2 -chlorobutane possesses a octanol-water partition coefficient less than four that leads to a prediction of low potential for bioaccumulation.

The substance 2 -chlorobutane is not expected to persist in the environment.
