Description

Description générale

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

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.

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.

Coupling agent for the spectrophotometric determination of aminophenols, phenylenediamines, dinitroanilines, chloroanilines, thiols, and sulfonamides.

Solution of N-(1-naphthyl)ethylenediamine dihydrochloride in sulfuric acid-methanol may be employed for the quantitation of sugars.
