Spectrophotometric Determination of Benzocaine by Azo-Dye Formation Reaction with N - (1-naphthyl)ethylenediamine as Coupling Agent
A simple spectrophotometric method for the determination of benzocaine in aqueous solution is developed. The method based on the coupling of diazotized benzocaine with N-(1-naphthyl)ethylenediamine(N-NED) in acidic<br />rnedium. The purplish - violet azo dye formed is water soluble, stable, an...
