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.

A high-pressure liquid chromatography (HPLC) assay for measuring picomole quantities of nitrosothiol in biological samples was developed. The assay utilizes the catalytic reduction of nitrosothiol by mercuric cation (Hg2+). Released nitrogen oxide reacts with sulfanilamide (SA) and N-(1-napthyl)ethylenediamine (NNED) to

A sensitive staining method for the detection of oxytocinase (EC 3.4.11.3) activity in electrophoresis gels has been described. The method is based on the enzymatic release of p-nitroaniline (PNA) from two specific synthetic oxytocinase substrates, S-benzyl-L-cysteine-p-nitroanilide (BCN) and L-leucine-p-nitroanilide (LN)
