Reference
A first endothermic peak, associated to solvent release, is observed between 25 and 170 °C. For the exothermic peak: Onset at 235.5 °C, Enthalpy = 12.7 J/g.
Description of key information
The test item decomposes before melting or boiling.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 846.88 °C
Additional information
The Boiling Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis. The test item between 25 and 170 °C releases solvent as shown on first endothermic peak, followed by decompositionbefore melting or boiling.
An estimated value with Mpbpwin v.1.43* using the following smile has been reported to perform the risk assessment:
[Na+].Nc1c2C(=O)c3ccccc3C(=O)c2c(Nc4ccccc4)cc1S(=O)(=O)[O-]
* 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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
