Cupferron is jargon for the ammonium salt of the conjugate base derived from '''N-nitroso-N-phenylhydroxylamine'''. This conjugate base is abbreviated as CU−. It once was a common reagent for the complexation of metal ions, being of interest in the area of qualitative inorganic analysis. Its formula is NH4[C6H5N(O)NO]. The anion binds to metal cations through the two oxygen atoms, forming five-membered chelate rings.

Nitrosobenzene is the organic compound with the formula C6H5NO. It is one of the prototypical organic nitroso compounds. Characteristic of its functional group, it is a dark green species that exists in equilibrium with its pale yellow dimer. Both monomer and dimer are diamagnetic.

Trifluoronitrosomethane (commonly abbreviated as TFNM) is a toxic and unstable gaseous compound consisting of a trifluoromethyl group covalently bound to a nitroso group. The gas is notable for its intense blue colour.

2-Methyl-2-nitrosopropane (MNP or t-nitrosobutane) is the organic compound with the formula (CH3)3CNO. It is a blue liquid that is used in chemical research as a spin trap, i.e. it binds to radicals.

chemical compound

'''S-Nitroso-N-acetylpenicillamine (SNAP''') is the organosulfur compound with the formula ONSC(CH3)2CH(NHAc)CO2H. It is a green solid.

Diazald ('''N-methyl-N-nitroso-p-toluenesulfonamide') is used as a relatively safe and easily handled precursor to diazomethane, which is toxic and unstable. Since its introduction in 1954, Diazald has become the favored commercially available precursor for the synthesis of diazomethane, compared to reagents like N-methyl-N-nitrosourea and N-methyl-N'''-nitro-N-nitrosoguanidine, which are less thermally stable and more toxic and mutagenic, respectively.

chemical compound

'''S-Nitrosoglutathione (GSNO') is an endogenous S''-nitrosothiol (SNO) that plays a critical role in nitric oxide (NO) signaling and is a source of bioavailable NO. NO coexists in cells with SNOs that serve as endogenous NO carriers and donors. SNOs spontaneously release NO at different rates and can be powerful terminators of free radical chain propagation reactions, by reacting directly with ROO• radicals, yielding nitro derivatives as end products. NO is generated intracellularly by the nitric oxide synthase (NOS) family of enzymes: nNOS, eNOS and iNOS while the in vivo source of many of t

1-Nitroso-2-naphthol is an organic compound with the formula . It is one of several possible nitrosonaphthols, and the most studied for applications as an indicator and a dye.
