Key value for chemical safety assessment

Additional information

The requirement to test the substance for melting point was waived in accordance with Colum 2 of REACH Annex VII because the substance has a melting point below -20°C. This is supported by available data from a secondary source, which indicates the melting point of the substance to be <-78°C.
