25 °C

Additional information

Based on the REACH Regulation, Annex VII, Column 2, the study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient. As seen in a DSC anlaysis, target substance does not melt up to 450 °C; decomposition occurs between 195 and 240 °C.

An estimated value of vapour pressure was used for the risk assessment. It was computed by MPBPWIN v.1.43 as implemented by EPISuite using the following smile notation:

CC(C)N(C(C)C)c2nn(C)(OS(=O)(=O)OC)c(/N=N/c1ccc(cc1)N(C)C)s2
