Properties
Cacodyl cyanide is a white solid that is only slightly soluble in water, but very soluble in alcohol and ether.[6]
Cacodyl cyanide is highly toxic, producing symptoms of both cyanide and arsenic poisoning. Bunsen described it[7] in the following terms;
This substance is extraordinarily poisonous, and for this reason its preparation and purification can only be carried on in the open air; indeed, under these circumstances, it is necessary for the operator to breathe through a long open tube so as to insure the inspiration of air free from impregnation with any trace of the vapor of this very volatile compound. If only a few grains of this substance be allowed to evaporate in a room at the ordinary temperature, the effect upon any one inspiring the air is that of sudden giddiness and insensibility, amounting to complete unconsciousness.
It is also explosive, and Bunsen himself was severely injured in the course of his experiments with cacodyl cyanide. The Russian military tested cacodyl cyanide on cats as a potential
