Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Not pyrophoric (based on chemical structure)
Not flammable in contact with water (based on chemical structure)
Key value for chemical safety assessment
Additional information
Comparison of the chemical structure with the functional groups listed in Recommendations on the Transport of Dangerous Goods, Manual of tests and criteria, Appendix 6, 5.3 (p. 442), indicates the substance is unlikely to be flammable on contact with water. In addition, experience in the handling and use of the substance has indicated no properties associated with flammability on contact with water. As a result, and according to Annex XI, section 1.2, based on the weight-of-evidence, testing for this endpoint is considered to be unnecessary.
Comparison of the chemical structure with the functional groups listed in Bretherick’s Handbook of Reactive Chemical Hazards, 6th Ed., Vol. 2, Pyrophoric materials (p. 343), indicates the substance is unlikely to have pyrophoric properties. In addition, experience in the handling and use of this substance has given no indication that it has pyrophoric properties. As a result, and according to Annex XI, section 1.2, based on the weight-of-evidence, testing for this endpoint is considered to be unnecessary.
Justification for classification or non-classification
The substance cannot be classified according to the criterium "flammability" as outlined in Regulation (EC) 1272/2008, Annex I, Part 2, 2.7 due to a lack of data. Therefore the outcome of self-classification is inconclusive even though the substance was shown to be not pyrophoric and not flammable in contact with water.
According to the additional criteria for classification 2.8.4.2, 2.10.4.1 and 2.12.4.1 respectively, of Regulation (EC) No. 1272/2008, Annex I, part 2, the substance shall not be classified as a self-reactive substance, a pyrosphoric solid or as a substance which in contact with water emits flammable gases respectively.
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.
