2.7-38.5 °C, OECD 102, O'Connor 2014

Key value for chemical safety assessment

Additional information

O'Connor 2014 conducted a study according to recent guideline using differential scanning calorimetry (DSC). The endotherm onset temperature was measured three times and interpreted as the melting point. The mean range 2.7 to 38.5 °C (276 to 312 K) explained by the presence of two geometric isomers in the substance, is selected to be carried forward for risk assessment and classification. The study is considered complete, adequate and reliable for the purpose of risk assessment and classification.
