Abstract
A method for purity analysis of dihydroxylammonium 5,5ʹ-bistetrazole-1,1ʹ-diolate (TKX-50) using high-performance liquid chromatography (HPLC) was established by optimizing the chromatographic conditions: the detection wavelength was set at 200 nm, and the sample was separated by reverse-phase column (SinoChrom ODS-BP, 4.6 mm × 200 mm, 5 μm) using binary mobile phase acetonitrile and water (volume ratio of 50/50) with a flow rate of 1.0 mL/min at column temperature of 25°C. Normalization method, external standard method, and internal standard method were used to analyze the purity of TKX-50. The results indicate that the precision and accuracy of each method can satisfy the requirements of product analysis; however, the external standard method possesses higher accuracy and precision by comparison and is suggested to analyze the purity of TKX-50.
