Application

N-(1-Naphthyl)ethylenediamine dihydrochloride dissolved in sulfuric acid-methanol may be used as a reagent for the determination of sugar on thin layer plates. It may also be used for the determination of sub-micromolar concentrations of nitrite ion after diazotisation with sulphanilic acid at low pH, by differential-pulse polarography. It may also be used as the coupling agent for the spectrophotometric determination of aniline by the diazotization-coupling method.

The Bratton-Marshall reaction can be used to identify patients with adenylosuccinate lyase deficiency. These patients excrete in their urine the dephosphorylated derivative of the de novo purine synthesis intermediate 5'-phosphoribosyl-4-(N-succinylcarboxamide)-5-aminoimidazole (SAICAR). The test described here depends on a coupling reaction
