After CR SB37 was filled in a volumetric flask of 10 ml, CR SB37 was weighed to be 8.3657 g.

Conclusions:

According to OECD 109, the density of CR SB37 was determined to be 0.83657 g/cm3 at 20 °C.

Executive summary:

This test using the procedures outlined in the ECIC Study Plan for 170215-03 and OECD 109. The density of the test substance was determined using the air comparison pycnometer method. Therefore, the density of CR SB37 was determined to be 0.83657 g/cm³at 20°C.
