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

The flammability of liquids is determined on basis of their flash point (in combination with their boiling point, the ability to emit flammable gases upon contact with water and their pyrophoricity. The substance has a high flashpoint (134°C) and a boiling point of 290°4C not indicating flammability. With regards to flammability in contact with water, the structural features of the substance were evaluated and it was concluded that the substance does not contain groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air (ECHA guidance R. No metals, transition metals, boron or silicon are present. Also, handling during the water solubility test confirms this conclusion. 
With regards to pyrophoric properties, evaluation of the structural features of the substance revealed that the substance does not contain any chemical group that might lead to spontaneous ignition a short time after coming into contact with air (ECHA guidance R.

Key value for chemical safety assessment

non flammable

Additional information

Justification for classification or non-classification

The substance as such being a liquid, is not considered flammable because its flash point is > 60°C. In addition, the substance is not considered flammable in contact with water and gas based on the results above. Therefore classification according to the CLP Regulation (EC) No. 1272/2008 is not needed.
