Additional information

Due to the results of the available test 2-methylbut-3-yn-2-ol is considered as poorly biodegradable. After prolonged test duration only poor biodegradation was observed. Hence it is concluded that the substance is persistent in the aquatic environment which is the main environmental compartment for environmental distribution. Consequently, further testing on the substance is not deemed necessary because it is already proven to be persistent.
