Chemical Properties
white to beige or pink powder
Uses
Usually used as a coupling agent for spectrophotometric analysis.
Uses
Determination of sulfanilamide
Uses
Coupling agent for the spectrophotometric determination of aminophenols, phenylenediamines, dinitroanilines, chloroanilines, thiols, and sulfonamides.1,2,3
Uses
N-(1-Naphthyl)ethylenediamine dihydrochloride acts as a coupling agent for the spectrophotometric determination of aromatic amines, aminophenols, phenylenediamines, dinitroanilines, chloroanilines, thiols and sulfonamides. It is also used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It is involved in the preparation of (N-1-naphthyl-ethylenediamine)-dichloroplatinum(II) by reacting with potassium tetrachloroplatinate.
