Conclusions:
A pycnometer was used for the determination of the density and relative density of the test substance. The density at 20 ºC was determined to be 0.933 g/cm3. The relative density was 0.933.
Executive summary:

The density and relative density of the test substance was dertermined in accordance with EU Method A.3 using the pyncometer method.

The density and relative density of (3R)-3-[(1R)-4-Methyl-3-cyclohexen-1-yl]butanal and (3S)-3-[(1R)-4-Methyl-3-cyclohexen-1-yl]butanal at 20 ºC was 0.933 g/cm3and 0.933, respectively.
