CAS 148823-36-3: H-D-Asp-OtBu

Description: H-D-Asp-OtBu, also known as tert-butyl L-aspartate, is a derivative of the amino acid aspartic acid. It features a tert-butyl ester group, which enhances its lipophilicity and stability compared to the free amino acid. This compound is typically used in peptide synthesis and as a building block in organic chemistry due to its ability to protect the carboxylic acid functionality of aspartic acid during reactions. The presence of the tert-butyl group also helps in improving solubility in organic solvents, making it suitable for various synthetic applications. H-D-Asp-OtBu is characterized by its specific stereochemistry, as it contains the L-configuration of aspartic acid, which is crucial for biological activity. Its molecular structure allows for participation in various chemical reactions, including coupling reactions in peptide synthesis. As with many chemical substances, proper handling and safety precautions should be observed, as it may pose risks if not managed appropriately.
