N- (1-naphthyl) ethylenediaminedihydrochloride

N- (1-naphthyl) ethylenediamine dihydrochloride is often used as a coupling agent for the spectrophotometric detection of aminophenols, phenylenediamines, dinitroanilines, chloroanilines, thiols and sulfonamides. The solution of N- (1-naphthyl) ethylenediamine dihydrochloride dissolved in sulfuric acid-methanol can be applied to the quantitative determination of sugars.
