Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11/1999 - 01/2000
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- not specified
- GLP compliance:
- yes
- Type of method:
- thermal analysis
- Remarks:
- (DTA, ISTA)
- Decomposition:
- yes
- Decomp. temp.:
- 100 °C
- Conclusions:
- There is no melting point up to the decomposition of the test substance at 100°C (EU method A1).
- Executive summary:
The melting point of the substance was tested according to EU method A1. 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. Exothermal decomposition of Imidoxim starts at 100 °C.

Description of key information
There is no melting point up to the decomposition of the test substance at 100 °C (EU method A1).
Various authors have reported melting points in a range of 136-155 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 100 °C
Additional information
- Should read > 100°C
- Pressure is not reported, but atmospheric pressure can be assumed
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
