Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- There is no melting point and no boiling point up to the decomposition of the test substance

- Pressure is not reported, but atmospheric pressure can be assumed.

Conclusions:
There is no boiling point up to the decomposition of the test substance at 100°C (EU method A1).
Executive summary:

According to EU method A1, no melting point and thus no boiling point up to the decomposition of Imidoxim at 100°C could be observed. The sample is closed up in a crucible made of glass for each run. First run (DTA): the sample is heated up in steps of 5 K and hold at each temperature for 25 minutes. In comparison with an inert sample (empty crucible) the temperature difference and the heat effect is recorded. Any thermal effect corresponds to a baseline deviation.

Description of key information

There is no boiling point up to the decomposition of Imidoxim at 100°C (EU method A1).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
100 °C
