- Conclusions:
- The relative density of Aldehyde M was determiend to be 0.9970 at 20 °C.
- Executive summary:
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of Aldehyde M. The density was determined in two independent determinations. Using the pycnometer method the density was determined to be 0.9970 ± 0.0001 g/cm3 at 20 ± 0.2 °C and the relative density was determined to be 0.9970 respectively. The standard deviation reflects the distinguished correlation of the two determinations. Thus, the study was regarded to valid.

Description of key information
The density of Aldehyde M was determined to be 0.9970 g/cm³ ± 0.0001 g/cm³ at 20 °C ± 0.2 °C and the relative density was determiend to be 0.9970 at 20 °C respectively.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.997
Additional information
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of Aldehyde M. The density was determined in two independent determinations. Using the pycnometer method the density was determined to be 0.9952 ± 0.0001 g/cm³ at 20 ± 0.2 °C. The standard deviation reflects the distinguished correlation of the two determinations. Thus, the study was regarded to valid.
