Sensitive and spectrophotometric methods for the determination of Azathioprine in tablets using indigo carmine and methyl orange
A simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of Azathioprine in tablet dosage form. Developed method is based on the formation of extractable colored complex of drug with colouring agent Indigo Carmine and Methyl orange. A wavelength maximum was found to be 683.7 nm and 566 nm. The concentration range of 15-50 μg mL-1 with of ...
متن کاملSpectrophotometric 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 کاملTitrimetric and Spectrophotometric Methods for the Determination of β-blockers in Pharmaceutical Dosage Form
Three new methods using titrimetric and spectrophotometry are described for the determination of Propranolol Hydrochloride (PPH) and Atenolol (AN) with potassium bromate as the oxidimetric reagent and acid dyes, Methyl orange and Indigo carmine. In direct titrimetric (method A), the drug is titrated directly with bromate in acid medium and in the presence of excess of bromide using methyl orang...

One titrimetric and two indirect spectrophotometric methods are described for the determination of doxycycline hyclate (DCH) in bulk drug and in its formulations. The methods use bromate-bromide, methyl orange and indigo carmine as reagents. In titrimetry (method A), DCH is treated with a known excess of bromate-bromide mixture in acid medium and the residual bromine is back titrated iodometric...
