Applicant's summary and conclusion
- Conclusions:
- The density of the test item R-Pantolactone was determined to be 1.250 g/cm³.
- Executive summary:
The purpose of the study was to determine the relative density of the solid test item at a specific
temperature by means of a gas comparison pycnometer.
The density of the test item R-Pantolactone was determined to be 1.250 g/cm³
(= 1.250 · 10³ kg/m³) at 19.8 °C ± 0.5 °C using a gas comparison pycnometer.
The relative density of R-Pantolactone was determined to be 1.250.
