2,2'-DITHIOBIS(5-NITROPYRIDINE)

Synonym(s):Bis(5-nitro-2-pyridyl) disulfide;DTNP

2,2′-Dithiobis(5-nitropyridine) was employed:

as cysteine-activating reagent to study the NMR of G protein-coupled receptors
in the deprotection assays for protected selenocysteine-containing peptides
for deprotecting p-methoxybenzyl groups and acetamidomethyl groups from the side-chains of cysteine and selenocysteine
to remove the p-methoxybenzyl protecting group from cysteine and selenocysteine side-chains

2,2′-Dithiobis(5-nitropyridine) is a cysteine-activating reagent and for deprotecting and removing p-methoxybenzyl groups and acetamidomethyl groups

2,2′-Dithiobis(5-nitropyridine) is an aromatic disulphide.
