摘要
为了控制抗高血压药物甲磺酸多沙唑嗪产品质量,对制备甲磺酸多沙唑嗪过程中产生的一个未知杂质进行了推测与合成。HPLC、LC-MS、NMR和IR确证所合成的化合物结构即未知杂质1-(4-羟基-6,7-二甲氧基-2-喹唑啉基)-4-(1,4-苯并二恶唑-2-甲酰基)呱嗪。
To perform the quality control of antihypertensive drug-Doxazosine Mesylate an impurity existed in the Doxazosine Mesylate products was synthesized and characterized. The experimental results indicated that the existence of the impurity was related to the hydrolyzation process. This impurity was synthesized and its structure was confirmed using HPLC, LC-MS, NMR, and IR.
