Abstract
2-Iodylbenzoate is proposed as an oxidimetric agent, in the presence of 4-N-methylaminophenol, for the spectrophotometric determination of primary aromatic amines. The purple-red product absorbs maximally at 525 nm and Beer's law is obeyed over a range corresponding to 4-32 mug/ml amine in the final solution. In contrast to dichromate or N-bromosuccinimide, previously used as the oxidant, 2-iodylbenzoate avoids errors arising from too large an excess of the oxidant, instability of the coupling intermediate, and the oxidation of the amine.
