Relative density at 20C:

Additional information

The bulk density of the DTPA-H5 powder of two different companies was ca. 625 and 750 kg/m3. With regard to the relative density, data from EDTA-H4 were used. These were 1.46 and 1.65 g/cm3. Therefore it was concluded that the density of DTPA-H5 was ca. 1.5 g/cm3.
