A stability-indicating reversed-phase high-performance liquid chromatographic assay procedure has been developed and validated for riluzole in the presence of alkaline and oxidative degradation products. The liquid chromatographic separation was achieved and compared isocratically on C18 Zorbax ODS and Poroshell 120 EC-C18 columns by using a mobile phase containing methanol-water, pH = 3.10 (70...

In this study, noncovalent functionalization of single-walled carbon nanotubes (SWCNTs) with phospholipid-polyethylene glycols (Pl-PEGs) was performed to improve the solubility of SWCNTs in aqueous solution. Two kinds of PEG derivatives, ie, Pl-PEG 2000 and Pl-PEG 5000, were used for the PEGylation process. An experimental design technique (D-optimal design and second-order polynomial equations...

A method for determination of alendronate sodium salt, clodronate disodium salt and etidronate disodium salt in pharmaceutical formulation by direct UV-spectrophotometry and/or first and second derivative UV-spectrophotometry via complex formation with Cu (II) ions is described. The calibration graphs are linear in the range 25-600 mmol/L for all the investigated compounds. No interference was ...
