2-methylbut-3-yn-2-ol is poorly biodegradable. 

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

To assess the biotic degradability of 2-methylbut-3-yn-2-ol a test according to EEC Directive 79/831, Annex V, Part C, 5.2 was performed (BASF 1989). This test guideline is similar to OECD TG 301F. As inoculum municipal activated sludge was used. After 28 days of exposure no biodegradation was measured (0% BOD/ThOD).
