Validated Colorimetric Assay of Clonidine Hydrochloride from Pharmaceutical Preparations
Clonidine hydrochloride is an antihypertensive agent used for migraine prophylaxis, attention deficit hyperactivity disorder, menopausal flushing and Tourette syndrome. The quantity of the active substance in pharmaceutical preparations must be within specific limits, in agreement with the respective label claim. Therefore, the aim of this study was to establish the conditions for two spectroph...

متن کاملSpectrophotometric assay of superoxide anion formed in Maillard reaction based on highly water-soluble tetrazolium salt.
A novel highly water-soluble tetrazolium salt, WST-1 (4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate sodium salt), can be reduced to water-soluble formazan with a superoxide anion. Here, the WST-1 assay was applied to detect the superoxide anion generated during the Maillard reaction. A sample solution containing carbonyl compounds such as glyceraldehyde and glyc...
متن کاملSensitive Spectrophotometric Determination of Tetracycline Hydrochloride Indosage forms using Sodium Nitroprusside and Hydroxylamine Hydrochloride
An optimized and validated spectrophotometric method has been developed for the determination of Tetracycline hydrochloride (TCH) in pharmaceutical formulations. The method is based on the reaction between TCH, sodium nitroprusside and hydroxylamine hydrochloride in alkaline medium. The product absorbed maximally at 529 nm. Beer’s law is obeyed in the working concentration range of 2-60 μg mL w...
متن کاملSolvent Extraction Spectrophotometric Determination of Vanadium Using Sodium Salt of 2-Mercapto-Pyridine-N-Oxide as a Reagent
A solvent-extraction spectrophotometric technique is proposed as a new method for determination of trace quantities of vanadium. Sodium salt of 2-mercapto-pyridine-N-oxide (thione) forms a complex with vanadium instantaneously. The purple 1:2 complex is formed of pH 2.3, easily extracted in chloroform and shows strong absorbance at 500 nm. The extracted complex is found to obey Beer's law i...
