Reference
Endpoint:
flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Description of key information

This substance is a liquid and therefore this endpoint is not relevant as i has been superceded by flash point and autoflammability.

There is no data available for 2,3 -dimethylbutane. Data is available for Hydrocarbons, C6, isoalkanes, <5%, n-hexane and Isohexane and this data is used for read across to 2,3 -dimethylbutane.

The upper and lower  flammability ranges for Hydrocarbons, C6, isoalkanes, <5% and n-hexane are 1.0 and 7.4 % v/v.

Key value for chemical safety assessment

Flammability:
flammable

Additional information

Justification for classification or non-classification

There is no data available for 2,3 -Dimethylbutane. Data is available for Hydrocarbons, C6, isoalkanes, <5% n-hexane and Isohexane and this data is used for read across to 2,3 -Dimethylbutane.

 

Based on available read across data, 2,3 -Dimethylbutane warrants classification as Category 2 for flammability (H225) under the Regulation (EC) 1272/2008 on

classification, labelling and packaging of substances and mixtures (CLP).
