Additional information

According to the REACH Regulation (EC n. 1907/2006) Annex VII Column 2, the study does not need to be conducted if the melting point is above 300°C. If the melting point is between 200°C and 300°C, a limit value based on measurement or a recognised calculation method is sufficient.

Acid Brown 214 decomposes at a temperature between 270 and 445°C, therefore 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])c6ccc(/N=N/c4cc(/N=N/c1ccc(cc1)[N+]([O-])=O)c(O)c(/N=N/c3cc(cc2cc(cc(O)c23)S(=O)(=O)O[Na])S(=O)(=O)O[Na])c4O)c5ccccc56

 

* 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).
