Applicant's summary and conclusion

Conclusions:

The relative density of the analogue substance was determined to be 1.71. It can be derived from the relative density of the analogue substance, which is much higher than 1, that the relative density of the substance subject of this registration will also be much higher than 1 (i.e. density of water) due to the comparability of the molecular structures of both the analogue and the substance subject of registration.
