Reference
Details:
The test item shows probably a melting area of the main component between -43 °C and 143 °C (in the 1. - 2. heating run) according to the definition in the OECD Guideline 102 (mean value from repeat determinations; 1stmelting).
-43 °C-143 °C (from first measurement)
-43 °C-144 °C (from second measurement)
-44 °C-143 °C (from third measurement)
The cooling runs show a crystallisation at 71 °C.
From 212 °C, the test item shows most probably a thermal decomposition and evaporation of the decomposition components.
Description of key information
-43 to 143 °C.
Key value for chemical safety assessment
Additional information
The melting range of the substance was determined by Differential Scanning Calorimetry according to OECD Guideline 102.
The temperature range represents the melting area of the main component.
The substance decomposes at ca. 212 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
