Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Deviations:
- no
- GLP compliance:
- no
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Estr-5(10)-ene-3,17-dione is classified as a not readily combustible solid. As a conclusion the substance is a non flammable solid.
- Executive summary:
Estr-5(10)-ene-3,17-dione in its delivery state melted when approached by the ignition flame. The substance did not burn up. Therefore, Estr-5(10)-ene-3,17-dione is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1. As a conclusion the substance is a non flammable solid.
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- other justification
- Justification for data waiving:
- the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
- Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

The substance in its delivery state was measured. The test substance melted when approached by the ignition flame. The substance did not burn up. No further testing was required.
Description of key information
a.) Flammability: Estr-5(10)-ene-3,17-dione is no flammable solid according to UN-MTC Procedure N.1.
b.) Pyrophoric properties: Estr-5(10)-ene-3,17-dione did not deliver indications of pyrophoric properties during the realization of other tests. The determination according to UN-MTC Procedure N.2 is not necessary.
c.) Contact with water: A review of the structure suggests that there are no chemical groups present that would imply pyrophoric properties or flammability on contact with water. A review of handling and used implies no pyrophoric properties or flammability on contact with water. Testing according to UN Procedure N.5 is not necessary.
Key value for chemical safety assessment
- Flammability:
- non flammable

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
