Description of key information

In accordance with REACH Annex XI this study is scientifically unjustified.  The flammability of liquids is determined on basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of Tetrabutane does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case. The flashpoint indicates that Tetrabutane has not to be classified as a flammable liquid. Tetrabutane was placed in this hazard class because it has a flash point of 124°C and the boiling point >253°C and therefore it does not meet not the criteria  for flammability.
