Materials and methods

Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)The water solubility of isobutane is 53.5mg/l
Executive summary:

The information is taken from a peer reviewed handbook which is considered reliable for assessment. The water solubility of isobutane is 53.5mg/l. As Isobutane is a C4 hydrocarbon the substance is considered adequate for read across.
