The purpose of this study is the development of a quantification method to detect the amount of amorphous cyclosporine using Fourier transform infrared (FTIR) spectroscopy. The mixing of different percentages of crystalline cyclosporine with amorphous cyclosporine was used to obtain a set of standar
A gas chromatograph/Fourier transform-infrared spectrometric analysis of benzophenones, as hydrolyzed products of benzodiazepine, was evaluated and the vapor phase spectra obtained were compared with those measured in the condensed phase. Each infrared spectrum obtained in the vapor phase showed a m
