Administrative data

Endpoint:
appearance / physical state / colour
Type of information:
other: No reported
Adequacy of study:
key study
Study period:
up to 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Source is a published handbook, no data on GLP/guideline compliance/method. Acceptable with restriction as handbook is peer reviewed and considered a reliable source.

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:
2-methylbutane is a volatile colourlrss liquid at 20oC and 1013hPa
Executive summary:

No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. Therefore 2-methylbutane is a volatile liquid or gas at 20oC and 1013hPa.
