Description of key information

The density of 1-hexyl-1H-pyrazol-4,5-diamine hemisulfate was 1.31 g/mL at 20°C, measured by the pycnometer method (OECD 109).

Key value for chemical safety assessment

Relative density at 20C:
1.31

Additional information

The density of 1-hexyl-1H-pyrazol-4,5-diamine hemisulfate was determined according to OECD 109 guideline (Density of Liquids and Solids) with the pycnometer method and following the GLP. The test was run in triplicate at 20°C.

~1.4 g of the test substance was placed into the sample cup of the multipycnometer. The test substance was equilibrated to 20°C in an incubator for ~3 hours. Three trials were conducted to determine the density of the test substance.

The density of 1-hexyl-1H-pyrazol-4,5-diamine hemisulfate was determined to be 1.31 g/mL.
