Spectrophotometric Determination of Pantoprazole Sodium in Pharmaceuticals Using N-Bromosuccinimide, Methyl Orange and Indigo Carmine as Reagents
Two sensitive spectrophotometric methods are presented for the assay of pantoprazole sodium sesqui hydrate (PNT) in bulk drug and in formulations using N-bromosuccinimide (NBS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve the addition of a known excess of NBS to PNT in acid medium, followed by determination of unreacted oxidant by reacting with a fixed a...
متن کاملSelective Spectrophotometric Determination of Metformin Hydrochloride in Pharmaceuticals and Urine Using Two Nitrophenols as Chromogenic Agents
Metformin hydrochloride (MFH) is an oral anti-diabetic drug of biguanide class. Two selective spectrophotometric methods were presented for the determination of MFH in pharmaceuticals. The methods were based on the measurement of yellow-coloured charge-transfer complexes formed between MFH and two poly-nitrophenols, namely, 2,4-dinitrophenol (DNP method, at 405 nm) and picric acid (PA met...
متن کاملSensitive, selective and extraction-free spectrophotometric determination of lamotrigine in pharmaceuticals using two sulphonthalein dyes
Two direct, simple, sensitive and rapid extraction-free spectrophotometric methods have been developed for the determination of lamotrigine (LMT) in pure form and in its dosage forms. The methods are based on formation of ion-pair complex between the drug and two sulphonthalein acidic dyes namely, bromothymol blue (method A) and bromocresol green (method B), followed by the measurement of absor...
