Colorimetric Determination of Phenylephrine Using 4-Aminoantipyrine

Spectrophotometric Determination of Phenylephrine Hydrochloride by Coupling with Diazotized 2- Aminobenzothiazole

“…Different spectrophotometric methods have been applied for the determination of phenylephrine with different reagents such as 4-aminoantipyrine in presence of periodate or alkaline ferricyanide (Al-Abachi and Al-Ward, 2002;Hiskey and Levin, 1960) , nitrous acid in presence of copper ion (Yahia and Laila, 1976) , chloranil (Amer et al, 1982) , ninhydrin in sulphuric acid (Muszalska et al, 2000), periodate (Neil and Gelenn, 1971), methylbenzothiazoline-2-one hydrazone in presence of iron (Gala et al, 1994), haematoxylin (Ibrahim;Alaa,2007), 4-aminophenol (Sane and Narkar,1980), chloramine (Szekerer et al, 1973), N,N-dimethylaniline hydrochloride with potassium ferricyanide (Tatsuzawa and Shimoda, 1968), hydroxyl ammonium chloride with cupric ion (Deodhar and Mehta, 1978), sodium borate (Doulakas, 1975), fluorodinitrobenzene (Tammilehto, 1975), bromothymol blue (Matthew et al,1972), and diazotized p-nitroaniline (Auerbach, 1950;Kelly and Auerbach, 2006). Also, the ultraviolet (Fabrizo, 2006) and derivative spectrophotometry (Kazemipour and Ansari, 2005) methods have been used.…”

Analysis of Acetaminophen, Phenylephrine Hydrochloride, Diphenhydramine Hydrochloride, and Ascorbic Acid in a Capsule Preparation

“…Two GLC procedures (3,4) for the quantitative de-termination of phenolic compounds have also been reported. No method for analyzing resorcinol and phenol quantitatively in each other's presence has been reported.…”

Spectrophotometric Determination of Acetaminophen, Phenylephrine Hydrochloride, Codeine Phosphate, and Pyrilamine Maleate in Tablets or Powder

“…o STANDARD ANALYTICAL PROCEDURE exists N for acetaminophen, codeine phosphate, phenylephrine hydrochloride, and pyrilamine maleate in this common pharmaceutical combination '; however, various assays were reported for each of the components alone or in other combination (1)(2)(3)(4). To achieve the separation of the components, the author employed a chromatography technique using alginic acid 40-100 mesh prepared after the process of Foster and Murfin ( 5 ) .…”
