Description of key information

Decomposition between 270 and 445 °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. Acid Brown 214  releases solvent between 127 and 198 °C, as shown on first endothermic peak, followed by decomposition of the product between 270 and 445 °C (onset at 292.9 °C, degradation enthalpy = 261.9 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).
