Z-L-tyrosine dihydrate - Introduction
N-Benzyloxycarbonyl-L-tyrosine (N-benzyloxycarbonyl-L-tyrosine) is an organic compound. The following is an introduction to its properties, uses, preparation methods and safety information:
Properties: N-benzyloxycarbonyl-L-tyrosine is a white crystalline powder with the structural characteristics of phenoxycarbonyl and tyrosine. It dissolves well in organic solvents such as dimethylformamide (DMF) or dichloromethane (DCM).
Purpose: N-benzyloxycarbonyl-L-tyrosine is commonly used in organic synthesis reactions, especially as a protecting group in polypeptide synthesis. By introducing it into the tyrosine molecule, undesired reactions of tyrosine with other compounds during the reaction can be prevented.
Preparation method: N-benzyloxycarbonyl-L-tyrosine can be obtained by reacting tyrosine with N-benzyloxycarbonyl chloride. First, tyrosine is dissolved in a sodium alkaline solution, then N-benzyloxycarbonyl chloride is added, and the reaction is promoted by magnetic stirring during the reaction. Finally, the reaction mixture is neutralized with aqueous ammonia or hydrochloric acid to obtain N-benzyloxycarbonyl-L-tyrosine.
Safety Information: N-Benzyloxycarbonyl-L-tyrosine does not cause serious harm to humans and the environment under routine experimental conditions. However, as a chemical, it still needs to be handled properly. Care should be taken to avoid contact with skin, eyes and inhalation during use and storage. Wear appropriate personal protective equipment such as lab gloves, goggles, and lab coats. Proper handling and storage of organic compounds is an important measure to ensure safety.
