Spectrophotometric Determination of Catecholamines in Pharmaceutical Preparations Via Charge Transfer Complex Formation Using Bromanil Reagent

Spectrophotometric Method for the Determination of Catechol Amines Drugs in Pharmaceutical Preparations

“…Catecholamine is an organic compound containing its watersoluble catechol (benzene with second hydroxyl side groups next to each other) and side amine series. 1 It can be derived from the amino acid tyrosine. The catecholamines include noradrenaline (noradrenaline), epinephrine (adrenaline), and dopamine.…”

“…Spectrophotometric methods carry out for the estima-tion of adrenaline utilizing different reagents like ferric chloride and chloranil, in the found of potassium hexa-cyanoferrate (III), or n the presence (1,10-phenanthroline). 1,4,[10][11][12][13][14][15] The values of the [(SD), and (RSD%)] for these imitate measurements of the drugs.…”

Spectrophotometric Determination of Catecholamine Containing Drugs Using Calcon Dye

“…Various spectrophotometric methods using different reagents have been reported for the determination of catecholamine drugs. These methods include ion association using eosin Y and application of cloud point extraction technique [26], charge transfer complexes using bromanil [27], oxidation-reduction using ferric ion [28][29][30], diazotisation using pnitroaniline [31], 4-aminoantipyrine in the basic medium [32], complexation reaction using 4-aminoantipyrine and copper ion, ionpair complex using triiodide ion [33] and using ferrous ion as a complexing agent in alkaline medium [34], oxidative coupling using p-toluidine in the presence of sodium periodide [35], 2, 6-diaminopyridine in the presence of potassium periodate [36] and 3methyl-2-benzothiazolinone hydrazone hydrochloride monohydrate in the presence of potassium ferricyanide [37].…”
