Description of key information

Mass median aerodynamic diameter: 107.34 µm
76.08% particles are > 100 µm
23.92% particles are between 10 µm and 100 µm (inhalable range)
0% particles are below 10 µm (throatic and respirable range)

Additional information

The particle size distribution of the test substance sample Reaction mass of 2-(3,4-dimethyl-1H-pyrazol-1-yl)succinic acid and 2-(4,5-dimethyl-1H-pyrazol-1-yl)succinic acid was determined using scanning electron microscopy according to OECD Guideline 110.
