Reference
7.35mg of sample heated at 10°C/min from 25°C to 500°C under nitrogen gas. Sharp endotherm observed at 115°C corresponding to the melting point. Black residue observed at the end of the run; 37% of starting mass.
The measurement was repeated with a 9.91mg sample from 50°C to ca. 450°C, with the similar results.
Description of key information
Decomposes without boiling at ca. 260 °C, EU Method A.2, DSC, Jackson 1999
Key value for chemical safety assessment
Additional information
Only a single study conducted according to guidelines and under GLP is available for this endpoint. The study is considered to be relevant, reliable (Klimisch 1) and adequate for the purposes of risk assessment, classification and labelling.
