Additional information

The substance 2-hexyldecanoic acid [4-(6-tert-butyl-7-chloro-1H-pyrazolo[1,5-b][1,2,4]triazol-2-yl)phenylcarbamoyl]methylester (UM-235) was observed to be a fine, off-white, free flowing powder by standard visual observation. Microscopic inspection revealed that the sample was made up of single crystalline particles which appeared to be sharp edged and irregularly shaped.


18.12% by volume of sample was seen to be ≤ 10.00 µm.
