Applicant's summary and conclusion

Conclusions:
According to the OECD109 guideline, EC Guideline A.3. and EPA OPPTS 830.7300, a gas comparison stereopycnometer was used for the determination of the density and relative density of D-ribose.
The density of the test item at 20ºC was 1.59 g/cm3 (1.59 x 10^3 kg/m3).
The relative density was 1.59.
