Description of key information

The flammability range of 2,4,4-trimethylpent-1-ene is 0.8-4.8%

Key value for chemical safety assessment

Flammability:
highly flammable

Additional information

The flammability range of 2,4,4-trimethylpent-1-ene is reported as 0.8-4.8%. This isomer is the major component of 2,4,4-trimethylpentene and so data for this isomer is considered relevant to fulfil this endpoint.This information is taken from the CRC Handbook which is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Justification for classification or non-classification

2,4,4 -trimethylpentene is a liquid and room temperature and on the basis of the boiling point (102°C) and flash point (-6°C) it will receive a classification of Category 2, hazard statement 'highly flammable liquid and vapour'.
