Cupferron
Encyclopedia
Cupferron, the ammonium salt of N-nitroso-N-phenylhydroxylamine, is a common reagent for the complexation
of metal ions. Its formula is
NH4[C6H5N(O)NO]. The anion binds to metal cations through the two oxygen atoms, forming five-membered chelate
rings.
Cupferron is prepared from phenylhydroxylamine
