Type:
relative density
Density:
1.479 g/cm³
Temp.:
20 °C
Conclusions:
The relative density of L-4-HYDROXYPROLINE is 1.479 g/cm³ at 20 °C.
Executive summary:

The relative density of L-4-HYDROXYPROLINE was determined using the gas comparison method at a temperature of 20 °C.

The determination of the relative density was performed by three-fold measurements of two independent test item samples.

The density of L-4-HYDROXYPROLINE was determined to be 1.479 g/cm³ (= 1479 kg/m³) at 20 °C.
