N-Bromophthalimide (NBP) is reported to be a stable oxidizing agent and is used as an oxidiometric titrate for the estimation of a variety of organic, inorganic and pharmaceutical compounds. The kinetics of oxidation of primary aliphatic amines by NBS in acid solution showed first order dependence on (NBS) and (amine). An increase in [H+] increased the rate marginally. The rate of reaction increased with decrease in the dielectric constant of the medium. The observed order of reactivity of different amines towards oxidation is: methyl
