What is examethyl disilaurea?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is it which has developed particularly rapidly in recent years. Do you know about it?
The official answer:White needle-like crystalline powder, non-toxic with a slight amine smell. It is an excellent silylation reagent, which can replace the active hydrogen atoms in organic molecules with trimethylsilyl groups, and is widely used in the pharmaceutical and chemical industries.
What’s the application of examethyl disilaurea?
An excellent silylation reagent that replaces the active hydrogen atoms in organic molecules with trimethylsilyl atom groups for use in the production of Cefalexin (Cephalexin IV) and Cephalexin VI. It is the ideal silylation protector for the synthesis of β-lactam antibiotics. In the case of Cephalosporin IV semi-synthesis, for example, the involvement of only BSU in the reaction results in extremely mild reaction conditions, fewer side reactions, and 2-3 times higher yields than other methods. It is of great practical value in the industrial production of antibiotics today.
