Evaluating the effect of oxygen on the rate of nitrosation of cysteamine. The solutions purged with argon (trace a) give a very slightly lower rate of nitrosation, indicating a small and insignifant contribution of nitrosation by N2O3. [CA]0 = 0.05 mol/L; [H+]0 = 0.08 mol/L; and [NO2−]0 = 0.07 mol/L. CA, cysteamine hydrochloride.
