Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Rationale for reliability incl. deficiencies:
data from handbook or collection of data
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. This is a peer reviewed handbook that has been cited by the US EPA in the EPISUITE modelling program. It is therefore accepted that this data source is reasonably reliable. US EPA. (2019).

The boiling point of 2,3-dimethylbutane is 58 °C.
Executive summary:

The boiling point of 2,3-dimethylbutance (58 °C) has been taken from the CRC Handbook. 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.

Description of key information

The boiling point of 2,3-dimethylbutane is 58°C.

Supporting data is available for Hydrocarbons, C6, isoalkanes, <5% n-hexane and Isohexane. Based on an analogue approach, this data is read across to 2,3 -dimethylbutane.

The boiling point range for Hydrocarbons, C6, isoalkanes, <5% n-hexane is 48°C to 70°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
58 °C
