Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test substance is an organic peroxide and is expected to decompose explosively before boiling, as is reported for the structural analogue cumene hydroperoxide (Ullmann, 2005). For read-across see chapter 13.

Key value for chemical safety assessment

Additional information

The test substance decomposes explosively before boiling under normal pressure. This is why during the production process a film evaporator under reduced pressure is used for concentration of the raw product. It can even be dangerous to try to determine the boiling point of the test substance under normal pressure.

According to Annex VII column 2, the study does not need to be conducted for substances which decompose before boiling (e.g. auto-oxidation, rearrangement, degradation, decomposition, etc.).
