Additional information

TATD-CLE is a white to off white, odourless substance used in the powder form.

Melting, boiling points and the vapour pressure were estimated using the calculation tool MPBPVP v1.43 [1]. Melting point resulted to be 349.84°C, boiling point 848.47°C and vapour pressure value 2.96E-021 mmHg, at 25°C.

The particle size distribution was reported by ACS DOBFAR [2] and the d(0.5) resulted in 115.3 µm, thus the substance is characterized by particles too large to pass in bronchi and lungs.

The partition coefficient octanol-water was estimated by KOWIN v.168 [3] tool and resulted 4.16.

TATD-CLE is solid at room temperature and through a wide range of temperatures, therefore the surface tension is a negligible property.

Furthermore flash point is only a relevant property for liquids, thus it does not need to be measured for substances that are solids or gases at room temperature.

TATD-CLE is non auto-flammable and is non-explosive

The rate of burn over 100 mm of TADT-CLE resulted to be 6 seconds and wetted zone stopped flame propagation for at least 4 minutes.

On the basis of this finding the substance resulted to have a flammability potential and it is, consequently, classified as Flam. Sol. 2, (H228), according to the CLP regulation.
