Description of key information

The vapour pressure is between 74 and 79 kPa at 20°C for 2-methylbutane based on calculated values.

Key value for chemical safety assessment

Additional information

The vapour pressure is between 74 and 79 kPa at 20°C for 2-methylbutane based on calculated values. This range has been agreed by the consortium to represent the substance. This is supported by a value of 100 kPa at 27.5°C 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.
