| Hazard Information | Back Directory | [Uses]
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
| [General Description]
2,2′-Dithiobis(5-nitropyridine) is an aromatic disulphide. |
