Additional information

According to Annex VII of the REACH Regulation EC n. 1907/2006, Column 2, the study does not need to be conducted for solids which either melt above 300 °C or decompose before boiling at ambient pressure (e.g. auto-oxidation, rearrangement, degradation, decomposition, etc.).

Decomposition of the test item beginning at 273 °C and no boiling was observed.

The estimated value of boiling point is 1267.45 (Adapted Stein & Brown method), MPBPVP v1.43, US EPA. [2016]. Estimation Programs Interface Suite™ for Microsoft® Windows, v 4.11]. United States Environmental Protection Agency, Washington, DC, USA. Smiles used:
