Conclusions:
A study was performed according to EU method A.3 and in compliance with GLP to determine the relative density of the test substance Reactive Red FC 73270. The relative density of of the test item is 1.64 at 22.8 °C compared to water at 4°C.
Executive summary:

A study was performed using air comparison pycnometer (for solids). The test was performed in two series with different amounts of test material, and each sample was measured in triplicate.

The relative density is 1.64 at 22.8 °C compared to water at 4 °C.

Description of key information

A study was performed following EU method A.3 in compliance with GLP.

The relative density of the test substance Reactive Red FC 73270 was determined to be 1.64.

Key value for chemical safety assessment

Relative density at 20C:
1.64

Additional information

Two test series with different weights were carried out in air at ambient temperature with a gas comparison pycnometer. The relative density of Reactive Red FC 73270 is 1.64 compared to water at 4 °C.
