Additional information

According to the REACH Regulation (EC n. 1907/2006), Annex VII, Column 2, the study does not need to be conducted if the melting point is above 300 °C. Based on the results of DSC analysis on the analouge , the substance is expected as not melting up to 300 °C but decomposing before melting, therefore the test does not need to be conducted.
