Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study without detailed documentation.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The flash point was estimated using the following methods:
1: The flash point was estimated from the LFL and vapour pressure data derived from the Company SDS
2. The flash point was estimated from the LFL calculated on the basis of the temperature and molecular weight of the substance according to the article " The relationship between flash point and LFL with application to hybrid mixures, R. W. Prugh, American Institute of chemical engineers process" - GLP compliance:
- no
- Type of method:
- other: The flash point of the substance is estimated using the Lower Flammability Limit (LFL)
- Flash point:
- -85.6 °C
- Atm. press.:
- 505 kPa
- Flash point:
- -130 °C
- Atm. press.:
- 1 atm
- Interpretation of results:
- study cannot be used for classification
- Remarks:
- The flash point is a relevant property for the determination of the hazardous classification for liquid substances only.
- Conclusions:
- The flash point of the substance is calculated -85.6°C at 505KPa (5 atm) and -130°C at 1 atm
- Endpoint:
- flash point of flammable liquids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a gas

Description of key information
The flash point is a relevant information for liquid only. As the substance is a gas the flash point determination is scientifically unjustified.
The flash point of the substance was calculated to be -130°C at 1 atm.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- -130 °C
Additional information
As the substance is a gas the flash point determination is scientifically unjustified. In fact, the flash point is a relevant property for the determination of the hazard classification for liquid substances only.
However the flash point of the substance below its boiling point (- 26°C) was calculated basing on the lower flammability limit (LFL) of 7% (v/v) according to the method described in the article "The relationship between flash point and LFL with application to hybrid mixures, R. W. Prugh, American Institute of chemical engineers process". The value was calculated to be -85.6°C at 5 atm and -130°C at 1 atm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
