- Type:
- relative density
- Density:
- 1.122 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The mean relative density D420 of the test item at 20 °C°C (compared to water at 4 °C) is D420 = 1.1221.
Reference
The density of the test item was determined twice with two independently prepared samples. The data, the mean of the densities, and its relative deviation are presented in Table 1 . Using the nominal density of water at 4 °C (0.999972 g/cm3), the relative density ()of Pyridine-2-aldehyde was determined to be = 1.1221.

Description of key information
The mean relative density at 20 °C is determinded to be 1.1221. It was determined in a reliable study conducted according to an appropriate standard tes method (OECD 109).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.122
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
