To calculate absolute density the following equation were used:

ρ = ((m3 - m0) / m3 - m0 + m2 - m4) ρx

Where:

ρ = density of the tested material at 20°C;

ρx = density of immersing liquid

To calculate relative density the following equation was used:

ρ204 = ρt / ρ4water

Where:

ρ = absolute density of tested material at 20°C, [g/ml];

ρ4water= density at 4°C temperature ca. 1.0000 g/ml;

ρ204 = relative density of the tested material, the absolute density in relation to water at 4°C.

Conclusions:
The relative density of Ethyl 5-sulfamoyl-o-anisate is 1.434 at 20ºC.
Executive summary:

Determination of relative density was carried out in accordance with the EU A.3 method, with GLP. The density determination of the tested material, using the Gay-Lussac pycnometer. The average measured absolute density of the tested material at 20°C temperature was 1.434 g/mL. The average calculated relative density of the tested material at 20°C temperature was 1.434.

Description of key information

Key study: EU method A.3. GLP study. The average calculated relative density of the tested material at 20°C temperature was 1.434.

Key value for chemical safety assessment

Relative density at 20C:
1.434
