Unsymmetrical dimethyl hydrazine is highly toxic, carcinogenic compound, widely used for organic synthesis and drug development. Therefore, due to its high reactivity, direct analysis is problematic. Current study proposes to use derivatization reaction to increase selectivity and sensitivity of high-performance liquid chromatography–mass spectrometry method. Different derivatization agents were tested
不对称二甲基肼是一种剧毒、致癌的化合物,广泛用于有机合成和药物开发。因此,由于其高反应性,直接分析是有问题的。目前的研究建议使用衍生化反应来提高高效液相色谱-质谱法的选择性和灵敏度。测试了不同的衍生剂并找到了最佳反应介质。通过使用少量试剂来进行衍生化以降低分析成本。对该方法进行了全面验证,可用于药物分析中的常规控制。方法灵敏度为 0.15 ppm,线性范围为 0.15–2.70 ppm。
