UV Spectrophotometric method for the identification and solubility determination of nevirapine

Die Pharmazie, 2009
An UV spectrophotometric method was developed for the quantitative determination of nevirapine in water, methanol and 0.1 N HCl. It was found that qualitative determination is also possible, due to a peak-shift observed with 0.1 N HCl. The solubility at 37°C, for both the anhydrous and hemihydrated forms of nevirapine, was determined in each of the ...

UV Spectrophotometric Method for Determination of Phenacetin in Biological Specimens

Journal of Pharmaceutical Sciences, 1973
A UV spectrophotometric procedure for determining phenacetin in biological specimens is described. The drug is extracted from biological material by ether and oxidized to a quinone product by cobaltic oxide. The primary metabolite of phenacetin, N-acetyl-p-aminophenol, is assayed by providing a salting-out step in the extraction process. Better than 90%

A New Method for The UV Spectrophotometric Determination of Mercury

Analytical Letters, 1973
Abstract Mercury forms a complex with 2-mercaptobenzoic acid which may be extracted into ethyl acetate to form the basis of a selective and sensitive method for the determination of mercury by solution spectrophotometry at 265 nm. Of twenty-nine ions investigated, only Cu2+, Co2+, Zn2+ and Fe3+ interfered at 100-fold molar excess.
