Description of key information

Additional information

The substance 2,3-dichloro-1,3-butadiene is not readily biodegradable, however, no significant environmental exposure is expected and therefore no further studies are provided.

According to OECD 111 (EC C.7) a hydrolysis test was performed in buffer solutions (pH 4, pH7, pH9) . All half-times are less than 2.4 hours at 50°C, therefore no additional tests at other temperatures had to be performed.

The substance 2,3-dichloro-1,3-butadiene is estimated to have a soil adsorption coefficient of 107 mL/g.
