Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

According to the REACH Regulation (EC) n. 1907/2006 Annex 7, Column 2, the study does not need to be conducted for solids which either melt above 300°C or decompose before boiling. The boiling point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis. The test substance does not boil but decompose: the DSC heating curve shows an endothermic peak, due to solvent evaporation, from 135 to 191 °C, (onset: 145.5 °C, Enthalpy = -37.4 J/g) followed by an exothermic peak, due to the decomposition of the product, from 303 to 415 °C (onset: 334.0 °C, enthalpy = 161.8 J/g).

An estimated value with Mpbpwin v.1.43* using the following smile has been reported to perform the risk assessment:



* Mpbpwin is an application contained in the EpiSuite 4.1, the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
