Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 110-44-1, Name is Sorbic acid, molecular formula is , belongs to quinuclidines compound. In a document, author is Gu, Jianhui, Formula: 112.13.
Convenient new synthesis of umeclidinium bromide
Umeclidinium bromide, a drug used for chronic obstructive pulmonary disease, is synthesized through a new intermediate of phenyl(quinuclidin-4-yl)methanone. This novel method with simple operation flow and cheap reagents, makes it suitable for scale up. The overall four-step process provides umeclidinium bromide in 29% yield and the purity up to 99.83%. The X-ray crystal structure of the drug molecule was first reported.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 110-44-1, in my other articles. Formula: 112.13.
