Additional information

According to ANNEX VII of REACH regulation n. 1907/2006, the study does not need to be conducted if the melting point is above 300 °C, and, if it is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient. The melting point falls in the range of 183 - 240 °C. A calculation method could not be used due to the inorganic nature of the substance. It is assumed the lowest possible vapour pressure for the calculation system for risk assessment.
