Conclusions:

The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 ''Boiling Point'' (July 1995).
The boiling range of 3,7-DIMETHYLOCTA-1,6-DIENE (batch FAB-11022018) should be stated at (160.0 - 167.6 +/- 0.1)°C or (433.1 - 440.8 +/- 0.3)K at 1013.25 hPa.

Executive summary:

The purpose of the study was to determine the boiling point of substance 3,7-DIMETHYLOCTA-1,6 -DIENE.

The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 “Boiling Point” (July 1995).

The boiling range of 3,7-DIMETHYLOCTA-1,6-DIENE (batch FAB-11022018) should be stated at (160.0.2 - 167.6 +/- 0.1)°C or (433.1 - 440.8.0 +/- 0.1)K at 1013.25 hPa.
