Description of key information

Decomposition between 303 and 415 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
349.84 °C

Additional information

The melting point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis. The tested substance does not melt 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:

O=S(=O)(O[Na])c1cccc3c1c4N=C%12[N+]6=C(N=C8c2ccccc2C7=NC9=[N+]5C(=Nc3n4[Cu-2]56N78)c%10ccccc9%10)c%11c(cccc%11%12)S(=O)(=O)O[Na]

 

* 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).
