Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adequacy of study:
key study
2 (reliable with restrictions)
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 Hazardous Substances Databank (HSDB). It is therefore accepted that this datasource is reasonably reliable.
Principles of method if other than guideline:
No method specified as data was obtained from handbook.

Key result
Substance type:
2,3-Dimethylbutane is reported to be a clear colourless liquid at ambient temperatures.
Executive summary:

2,3-Dimethylbutane is reported to be a clear colourless liquid at ambient temperatures according to Hawley's Condensed Chemical Dictionary.

Description of key information

2,3 -Dimethylburtane is a colourless liquid at 20°C and under normal pressure.

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.

Hydrocarbons, C6, isoalkanes, <5% n-hexane is a clear colourless liquid with a slight odour at 20°C.

Key value for chemical safety assessment
