Description of key information

Diarsenic trioxide is a crystalline powder. The particle size distribution of a typical commercial sample has been determined experimentally (laser diffraction method, OECD 110, GLP). The material is characterised by a median particle diameter D50 = ca. 38 µm (D10 = ca. 2 µm, D90 = ca. 153 µm).
