General description

N-(1-Naphthyl)ethylenediamine dihydrochloride (NEDA·2HCl) acts as donor molecule and forms charge transfer (CT) complexes with π-acceptors (quinol and picric acid), σ-acceptors (iodine) and vacant orbital acceptors (tin(IV) tetrachloride and zinc chloride). These complexes were investigated by positron annihilation lifetime spectroscopy (PAL).

Application

Solution of N-(1-naphthyl)ethylenediamine dihydrochloride in sulfuric acid-methanol may be employed for the quantitation of sugars.
N-(1-Naphthyl)ethylenediamine dihydrochloride may be used in the synthesis of 5-[1,2]dithiolan-3-yl-pentanoic acid [2-(naphthalene-1-ylamino)-ethyl]amide (DPAN) by reacting with (±)-1,2-dithiolane-3-pentanoic acid in the presence of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride and N-hydroxysuccinimide. The solution formed by dissolving N-(1-naphthyl)ethylenediamine dihydrochloride in sulfuric acid-methanol may be used as a reagent for the detection of sugars at nanoscale on thin-layer plates.
N-(1-Naphthyl)ethylenediamine dihydrochloride has been used for the preparation of staining solution for the visualization of the reaction product(s) of starch active enzymes, containing α-1, 4 linked and α-1, 6 linked glucose by thin layer chromatography. It has also been used in modified Saville and Griess assays.
Coupling agent for the spectrophotometric determination of aminophenols, phenylenediamines, dinitroanilines, chloroanilines, thiols, and sulfonamides.
