Description of key information

The median particle size of 5,5'-Dithiodi-1,3,4-thiadiazole-2(3H)-thione is 6.456 µm, with a mass median aerodynamic diameter of 4.554 µm.  The particle size distribution is 10% of the substance <2.719 µm, 50% of the substance <6.456 µm, and 90% of the substance <11.816 µm (Intertek Pharmaceutical Services Manchester, 2014d).
