Introduction
N-Boc-L-aspartic acid is an L-methionine derivative containing an N-protecting group.
Quality:
N-Boc-L-methionine is a white solid that is soluble in some organic solvents such as methanol, ethanol, and methylene chloride. It is stable in acidic conditions but hydrolyzed in alkaline conditions.
Use:
N-Boc-L-methionine is a commonly used amino acid protecting group that protects other reactive groups in the synthesis of organic compounds.
Method:
The preparation of N-Boc-L-methionine is usually achieved by the chemical reaction of the N-Boc protecting group on L-methionine. A common method is to use Boc2O (N-butyldicarboxamide) and a base catalyst to give N-Boc-L-methionine after the reaction.
Safety Information:
N-Boc-L-methionine is generally relatively safe under conventional experimental operating conditions. It can be irritating to the eyes, skin, and respiratory tract and care should be taken to avoid contact when using it. Pay attention to abide by the safety experiment operation specifications and be equipped with corresponding protective measures.
