UV-Visible spectrophotometry of Repaglinide in bulk and in formulation by using methyl orange as reagents

Two sensitive spectrophotometric methods are presented for the assay of Repaglinide in bulkdrug and in formulations using methyl orange, as reagents. Oxidant by reacting with a fixedamount of either methyl orange and measuring the absorbance at 485.2 nm (method-I) andmeasuring the absorbance at 618.9 nm (method-II). Developed method is based on the formationof extractable colored complex of dru...

Determination of Triiodide Ion Concentration Using UV-Visible Spectrophotometry†

The concentration of iodine species can be measured using several different analysis methods. One of the most wellknown methods involves iodine titration with a thiosulfate solution. Total iodine can be analyzed using spectrometry, such as inductively coupled plasma-atomic emission spectrometry (ICP-AES), atomic absorption spectrometry (AAS) and inductively coupled plasma-mass spectrometry (ICP...
