- Conclusions:
- The density of the substance is 1.2135 ± 0.0002 g/cm^3.
- Executive summary:
Using the pycnometer method, a density of 1.2135 ± 0.0002 g/cm3 was measured. This value is the mean of two independent determinations with the maximum error of the single determination. Temperature was 20.0 ± 0.2 °C. Standard deviation was 0.0006 g/cm3, showing good correlation of the two determinations.
Reference
The density of the test item 2,2'-azobis(2 -amidinopropane)dihydrochloride was calculated as 1.2135 ± 0.0002 g/cm3 at 20.0 °C, which is the mean of two values. Precision of the value is given as maximal error of the single determination.
The standard deviation of the two values is only slightly higher than the maximal error of the single determination. Correspondence of the values is very good. Therefore the study is considered valid.
Description of key information
The density of the substance is 1.2135 ± 0.0002 g/cm3.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.214
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).
