Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 340 °C
- Remarks on result:
- other: no melting point up to decomposition
Applicant's summary and conclusion
- Conclusions:
- The study was performed according to EU method A.1 with acceptable restrictions (no GLP) and therefore reliability of Klimisch 2 has been assigned. The substance decomposes at 340 °C without melting.
- Executive summary:
The screening-DTA (closed glass crucible, heating rate 3 K/min, no GLP) of the sample Iminopyrazolsäure shows no melting point, but decomposes above about 340 °C with a heat release of about 180 kJ / kg. ‘Iminopyrazolsäure' exhibits no melting point up to 340 °C according to EC A.1.
