boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Up to 2008
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: No data on GLP/guideline compliance but handbook is peer reviewed and considered a reliable source.
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.
GLP compliance:

Not reported

Key result
Boiling pt.:
49.3 °C
Atm. press.:
760 mm Hg
Remarks on result:
other: (101.325 kPa)
The boiling point of cyclopentane was measured as 49.3 °C (at 760 mm Hg).
Executive summary:

There is no available information on the methods used to determine the value for this endpoint. However, this information is taken from the CRC Handbook which is considered to be a reliable peer reviewed handbook and suitable for use as the key study for this endpoint. Therefore the boiling point of cyclopentane is 49.3 °C (at 760 mm Hg).

Description of key information

The boiling point range for cyclopentane is between 48°C and 50°C based on ASTM D 1078 methodology.

Key value for chemical safety assessment

Additional information

The boiling point is 48 to 50°C for cyclopentane, based on ASTM D1078 methodology. This range has been agreed by the consortium to represent the substance. This is supported by a value of 49.3°C (at 760 mm Hg) from the CRC Handbook (Lide 2008). There is no information available on the methods used to determine the value for this endpoint. However, the CRC Handbook is considered to be a reliable, peer-reviewed handbook and suitable for use as a study for this endpoint.
