Additional information
Based on the REACH Regulation, Annex VII, Column II, the study does not need to be conducted if the melting point is above 300 °C. Basic Blue 159 decompose at temperature between 195 and 240°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. Basic Blue 159 decomposes at a temperature between 195 and 240 °C.
An estimated value with Mpbpwin v.1.43* using the following smile has been reported to perform the risk assessment:
CC(C)N(C(C)C)c2nn(C)(OS(=O)(=O)OC)c(/N=N/c1ccc(cc1)N(C)C)s2
* 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).
