Two test series were performed at 20.0 °C. The results are summarized in Table 1:

Table 1: Results of the two tests

Measurement	Density ρ(PR) / g / cm³
1	1.2778
2	1.2823
Mean	1.2801

The mean density for the two test series is 1.28 g/cm³. Thus, the relative density (compared to water at 4 °C) is 1.28 ± 0.01.

Conclusions:

The relative density of the test item 4,4’-Dimethoxytrityl chloride was determined according to the European Commission Regulation (EC) No. 440/2008 and OECD 109 by gas comparison pycnometer method and is 1.28 at 20 °C.

Executive summary:

The relative density of the test item 4,4’-Dimethoxytrityl chloride was determined according to the European Commission Regulation (EC) No. 440/2008 and OECD 109 by gas comparison pycnometer method and is 1.28 at 20 °C.
