Product Description

Product Name:                 L-Asparagine Monohydrate

CAS No:                          5794-13-8

Product Description

L-asparagine monohydrate and its derivatives are important organic structural units, and have been widely used in the fields of drug synthesis, food addition and new material synthesis. The amino group, carboxyl group and amide group contained in L-asparagine monohydrate are all functional groups with high reactivity. In order to prevent the amino group from being affected during the reaction of carboxyl or amide group in L-asparagine monohydrate, it is often necessary to selectively protect the amino group with easily removed protective groups. The amino group is often protected by first allowing the amino group to react to form a more stable amide, ester or imine, etc., and then using a suitable method to remove the protective group
L-asparagine monohydrate, as one of the amino acid derivatives, is a very important organic synthesis molecule. Recent studies have shown that the compounds obtained from the monohydrate of L-asparagine have high medicinal value, showing good biogenic activity in anti-inflammatory, hypotensive, hemostatic and other aspects. In addition, L-asparagine monohydrate and its derivatives are widely used as important organic molecules in food science, medicinal chemistry and materials science. At present, there are three methods for preparing L-asparagine monohydrate, including direct extraction, chemical synthesis and biological conversion.
