Reference
The test item showed a broad melting range from about -30 °C to 42 °C with two distinct endothermic peaks at -10 °C and 37°C peak temperature.
Observed thermic processes:
A 3rd endothermic peak was found in Test 1 at 10 °C peak
temperature. Between determination A and 8 , small discrepancies were
observed around 0°C with no influence on the resulting melting range.
In order to survey the thermic behavior of the test item, a
TG/DSC-Test (non-GLP) was run up to 600 °C.
A stepwise weight lass starting at about 50 •c with a total weight lass
at about 200 •c showed the vaporization of the test item.
Description of key information
Melting range: about -30°C to 42°C
Key value for chemical safety assessment
Additional information
The determination was conducted by DSC according to OECD Guideline 102.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
