Uv Derivative Spectrophotometric Method for Determination of Estradiol Valerate in Tablets
A derivative UV spectrophotometric method for determination of estradiol valerate in tablets was validated. The parameters specificity, linearity, precision, accuracy, limit of detection and limit of quantitation were studied according to validation guidelines. The first-order derivative spectra were obtained at N = 5, ∆λ = 4.0 nm, and determinations were made at 270 nm. The method showed speci...
متن کاملDetermination of Diflunisal in Tablets Using Derivative UV Spectrophotometric Methods
In this study, derivative UV spectrophotometric methods were developed for the analysis of diflunisal, which is used as a nonsteroidal anti-inflammatory drug. Analysis wavelengths of diflunisal for the first and second order derivative UV spectrophotometric methods were obtained as 235.6 nm and 228.8 nm, respectively. The linearity ranges were found as 1.0-25.0 μg mL-1 for the first order and 1...
متن کاملDevelopment and Validation of an UV-Derivative Spectrophotometric Method for Determination of Glimepiride in Tablets
A glimepirida é um fármaco antidiabético oral usado no tratamento da diabetes tipo 2. Este trabalho propôs o desenvolvimento e validação de um método por espectrofotometria derivada na região do ultravioleta para determinação de glimepirida em comprimidos. A quantificação de glimepirida em solução de NaOH 5×10 mol L foi realizada usando um intervalo de 8 nm entre 220 a 300 nm. Os valores de amp...
متن کاملDerivative Spectrophotometric Method for Determination of Losartan in Pharmaceutical Formulations
Losartan, a highly effective blood pressure lowering agent, has been widely used for the treatment of hypertension. A fast and reliable method for the determination of losartan was highly desirable to support formulation screening and quality control. A first derivative UV spectroscopic method was developed for determination of losartan in the tablet dosage form. The first derivative spectrum r...
متن کاملDetermination of Estradiol Valerate in Pharmaceutical Preparations by Zero - and First-order Derivative Spectrophotometric Methods
This paper describes zeroand first-order derivative spectrophotometric methods for determination of estradiol valerate in pharmaceutical preparations. The solutions of the standard and pharmaceutical samples were prepared in methanol. Absorbances of estradiol valerate were measured at 280 nm for zero-order by measuring height of peak from zero, at 292 nm for first-order derivative spectrophotom...
