Description of key information

Half-life: 2 hours

Key value for chemical safety assessment

Half-life in air:
2 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

The calculated half-life of 2 hours (ISP, 2010) indicates that 1,4 -butenediol will react with hydroxyl radicals in the atmosphere and that there is little or no potential for long-range transport.
