On July 31, 2020, Yu, Wen-Shuai; Wu, Ze-Nong; Qiu, Zeng-Feng; Zhao, Chun-Jie; Zhang, Fu-Li; Yang, Zhe-Zhou published an article.Category: ethers-buliding-blocks The title of the article was One-Pot Synthesis of Papaverine Hydrochloride and Identification of Impurities. And the article contained the following:
A one-pot synthesis of papaverine hydrochloride with 99.6% purity was performed using xylene as solvent for the entire process. The critical parameters of each step, as well as the impurities generated, were identified. The overall yield was improved to 63%. The proposed synthetic procedure was suitable for industrial production The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Category: ethers-buliding-blocks
The Article related to papaverine hydrochloride preparation, Alkaloids: Alkaloids Containing One Nitrogen Atom In A Ring and other aspects.Category: ethers-buliding-blocks
