Product Description

1,3-Bis(trimethylsilyl)urea, English abbreviation BSU, white needle-like crystalline powder, non-toxic slightly amine taste. It is an excellent silanizing reagent, which can replace active hydrogen atoms in organic molecules with trimethylsilicon atomic groups, and is widely used in the field of medicine and chemical industry.

Uses: It is an excellent silanizing reagent [2], which can replace active hydrogen atoms in organic molecules with trimethylsilicon atomic groups, and is used in the production of cephalosporin (cephalosporin IV) and cephalosporin VI. This product is the best silanizing protective agent in the synthesis of β-lactam antibiotics. Taking the semi-synthesis of cephalosporin IV as an example, the reaction condition can be extremely mild, the side reaction is less, and the yield is 2-3 times higher than other methods. It has great practical value in the industrial production of antibiotics today.

Packing: Cardboard drum or plastic drum lined with plastic bag, net weight: 25kg.
