Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
Endpoint:
flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Endpoint:
pyrophoric liquids
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 known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

a) Flammability: The flammability of liquids is determined on basis of their flashpoint (in combination with their boiling point).
b) Flammability on contact with water: In accordance with section 1 of REACH Annex XI, the study on flammability in contact with water does not need to be conducted as the substance contains no metals or metalloids and therefore will not release flammable gases in contact with water
c) Pyrophoric properties: In conclusion based on the known flash point of pentanoic anhydride it is considered not to be flammable. Based on the absence of structural alerts and experience in handling and use negative results are predicted for pyrophoric properties.

Key value for chemical safety assessment

Flammability:
