- Laser light scattering. The test was performed according to the SOP 071 Ed.03 (Hydro 2000S-A) protocol.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. - GLP compliance:

- solid
- Form:
- powder
- Substance type:
- organic
- Conclusions:
- The test substance is a solid at 20°C and 101325 Pa (MMD = 29.777 µm).
- Executive summary:
Methods:
The substance has been tested for granulometry by the volumetric distribution. The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It measures the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.

Method:
Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results:
Between 165 and 207°C it is observed a first endothermic event (onset = 191.3°C, enthalpy = -97.4 J/g) followed by a second endothermic event between 249 and 295°C (onset = 257.6°C, enthalpy = -98.9 J/g) and by an exothermic event between 295 and 379°C (onset = 313.0°C, enthalpy = 623.1 J/g).
Conclusion:
The test substance is a solid at 1013 hPa in a range of 25°C and 165°C.
