Additional information

The melting point determination of Test item 2-butyl-6-(butyl amino)-1H-benz[de]isoquinoline-1,3(2H)-dione (CAS No. 19125-99-6) was done as per the test guideline OECD 102. The method followed was according to capillary/metal block. The melting range was found to be 110.8°C -118 °C at 972.4hPa. There was no decomposition observed.

Other supporting data from authoritative database and handbook indicates the melting point to be in the range of 123 - 349.84°C

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of melting point as 110.8°C -118 °C, thus considered as key study for chemical safety assessment.
