Description of key information
The water solubility of 2-methylbut-2-ene is 193 mg/L at 25⁰C. This classes the substance as moderately soluble (100-1000 mg/L). This value can be used as read-across for isoamylene (2-methylbutene, CAS 26760-64-5).
Key value for chemical safety assessment
- Water solubility:
- 193 mg/L
- at the temperature of:
- 25 °C
Additional information
The key study, Hine et. al. (1982) was given a reliability rating of 2, because the data are not from the primary source, but rather from reviewed, acceptable data. Used as the key study for OECD SIDS (2005) for513-35-9 and given a reliability 2. The water solubility of 2-methylbut-2-ene is 193 mg/L at 25°C. This classes the substance as moderately soluble (100-1000 mg/L). Since isoamylene (2-methylbutene,26760-64-5) is a mixture of the two isomers, 2-methylbut-2-ene (513-35-9) and 2-methylbut-1-ene (563-46-2) and in the absence of any reliable data for isoamylene then 2-methylbut-2-ene is considered a suitable substance for read-across.
