- Executive summary:
The melting point/range of the test item was investigated in a GLP-compliant study performed in accordance with EU Method A.1 (Melting / Freezing Temperature) and OECD Guideline 102 (Melting point / Melting Range). No melting point of the test item was observed over the range -100°C to +70°C.
Reference
Three assays were performed during the test but no melting point was observed.
Description of key information
The melting point/range of the test item was investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with EU Method A.1 (Melting / Freezing Temperature) and OECD Guideline 102 (Melting Point / Melting Range). No melting point of the test item was observed over the range -100°C to +70°C.
Key value for chemical safety assessment
Additional information
The melting point/range of the test item was investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with standard methods, without deviations. The study is considered as reliable without restriction (Klimisch 1) and was selected as key study for the endpoint.
