Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stable at room temperature (OECD 113, Williams, 2011)
Onset of first exotherm detected at 280 ºC with a heat of decomposition of 737 J/g (DSC, Bailey, 2012)
Compatible with an oxidising agent (sodium hypochlorite solution), a reducing agent (iron powder), water and a fire extinguishant (mono-ammonium phosphate solution) (oxidation/reduction - chemical incompatibility, OCSPP 830.6314, Jackson, 2010)
Additional information
Justification for classification or non-classification
"Self-reactive substances and mixtures":
The heat of decomposition measured in the screening test was > 300 J/g. However further data and expert judgment lead to the conclusion, that the substance does not have to be classified for this hazard. However further assessment and maybe further tests are needed for a conclusive statement. Thus the following conclusion is not definitive:
Based on the available information the substance does not meet the criteria for classification as a "self-reactive substance" under Regulation (EC) 1272/2008, Annex I, Part 2, 2.8.2; reason for non-classification: inconclusive.
"Self-heating substances and mixtures":
According to the Guidance on the Application of the CLP Criteria (ECHA-12-G-06-EN, Version 2.0, April 2012, p 151), substances with a low melting point (< 160 °C) should not be considered for classification in the "self-heating substances and mixtures" hazard class, if the substance is completely molten up to this temperature. The pure substance has a melting point of 148.4 °C.
Based on the available information the substance does not meet the criteria for classification as a "self-heating substance" under Regulation (EC) 1272/2008, Annex I, Part 2, 2.11.2; reason for non-classification: conclusive but not sufficient for classification.
"Corrosive to metals":
Based on Regulation (EC) No 1272/2008 (CLP), Annex I, 2.16.2.1, the Guidance on the Application of the CLP Criteria (ECHA-12-G-06-EN, Version 2.0, April 2012, p 191) states that only substances, for which the application of the test “C.1” described in part III, section 37 of the UN-MTC (4th revised edition) is relevant, need to be considered for classification in the “corrosive to metals” hazard class. The given test ist only applicable for liquids and "solids that may become liquid during transport". The technical grade substance is a solid (melting point of the pure substance: 148.4 °C), thus the test is not applicable.
Based on the available information the substance does not meet the criteria for classification as a "corrosive to metals" under Regulation (EC) 1272/2008, Annex I, Part 2, 2.16.2; reason for non-classification: conclusive but not sufficient for classification.
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.
