چکیده
|
Diazepam reacts with ninhydrin at ph range 12-12.5 to give a violet color having maximum absorbance at 530 nm wavelength. the reaction is specific for diazepam and provides a basis for its spectrophotometric determination. the color reaction obeys beer's law from 0.1 to 2 mg/10 ml of diazepam. coefficient of variation and confidence limit determination are 0.06 and 0.0041%,respectively. the relative standard deviation is 1.5%. the quantitative assessments of tolerable amount of other drugs have also been studied.
