- Expiration date: 31 December 2017
- Storage condition: at room temperature

Key result

Melting / freezing pt.:

< -60 °C

Decomposition:

yes

Decomp. temp.:

>= 224 °C

Decomposition was observed to commence at 224°C (mean of 222°C (test 1) and 226°C (test 2)).

Conclusions:

The melting/freezing temperature of the test substance was determined to be < -60°C.

Description of key information

From a GLP study (K1, Foster, 2016) according to the EU method A.1 and OECD guideline 102, the melting/freezing temperature of the test substance was determined to be <-60°C.
