Abstract: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.
Key words:Doxazosine Mesylate; unknown impurity; hydrolyze; confirmation
