Off white powder

Safety Profile

Moderately toxic byintraperitoneal route. Mutation data reported. Whenheated to decomposition it emits very toxic fumes of HCland NOx.

Purification Methods

Purify the salt by treating an aqueous solution with saturated Na2S2O3, filtering under N2, then recrystallising it from 50% EtOH twice and once from absolute EtOH [Livingston & Ke J Am Chem Soc 72 909 1950]. [Beilstein 13 III 993.]
