Key value for chemical safety assessment

Additional information

Discussion for CAS# 297730-93-9:

Density of CAS# 297730-93-9 was assessed in three studies. In the key study, CAS# 297730-93-9 had a measured density of 1.63 g/cm3 at 20°C, as determined by a pycnometer method. The two supporting studies were obtained from reference materials. The first supporting study was a primary publication. A density of 1.639 g/mL at 25 ° (298 K) was obtained using pycnometry. The second supporting study, a vendor MSDS, reported a density of 1.61 g/mL but did not specify either the temperature at which the density was measured or the method used.


The key study was performed in accordance with OECD TG109 and was compliant with GLP-standards. The supporting studies were not noted as GLP-compliant, no standard method was cited, and only summary data were provided. The reliability of the supporting studies cannot be assessed at this time.
