“…There is a continuing need for developing new method to improve the sensitivity of detecting DAAF. High‐performance liquid chromatography (HPLC) has much more sensitivity and reliability than electro‐analysis, so HPLC is a very important tool for the analysis of energetic materials . However, there is only one literature about the HPLC method of DAAF at present.…”

Diamino-4,4-azoxyfurazan (DAAF) as a promising energetic material, has many potential applications in both civil and military areas. High-performance liquid chromatography (HPLC) is an important analytical method for quality control and environmental monitoring of DAAF. In this study, chromatographic conditions of DAAF were optimized to develop an analytical method based on HPLC-DAD. DAAF and its byproducts were separated within 13 min with DAAF's retention time of 8.690 min and the resolution of all peaks were above 1.5 with high number of theoretical plates (N > 54259) under optimum condition of HPLC. Meanwhile, the method was validated and showed good performance for quantitative analysis of DAAF with LOD of 0.19 ng and linearity range from 0.84 to 211.16 μg mL À 1. Furthermore, the method was applied to the analysis of the purity of DAAF for quality control of different preparation stages and trace DAAF in wastewater for environmental monitoring around explosive manufacturing.
