Executive summary:

The purpose of the study was to determine the relative density of the test item 3-aminophenol at a specific temperature by using a gas comparison pycnometer, according to the A3 method and OECD 109 guideline, and following the GLP. The relative density of the test item

3-aminophenol was determined using the gas comparison method at a temperature of 20 ± 0.5 °C. The determination of the relative density was performed by three-fold measurements of two independent test item samples. The relative density of the test item 3-aminophenol was determined to be 1.276 g/cm³ (= 1276 kg/m³) at 20 °C.

Description of key information

The relative density of the test item 3-aminophenol was determined to be D4/20= 1.276 g/cm³.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The purpose of the study was to determine the relative density of the test item 3-aminophenol at a specific temperature by using a gas comparison pycnometer, according to the A3 method and OECD 109 guideline, and following the GLP. The relative density of the test item3-aminophenol was determined using the gas comparison method at a temperature of 20 ± 0.5 °C. The determination of the relative density was performed by three-fold measurements of two independent test item samples. The relative density of the test item 3-aminophenol was determined to be 1.276 g/cm³ (= 1276 kg/m³) at 20 °C.

Other supporting data from authoritative databases also determined the density of 3-aminophenol as 1.195 g/cm³ and 0.99 g/cm³ at 25°C.
