Description

Used for colorimetric determination of sulfonamide in bloodN-(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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
