Boc-D-Asp-OtBu

Description:

Boc-D-Asp-OtBu, also known as tert-butyl (2S)-2-amino-4-(carboxymethyl)pentanoate, is a protected derivative of aspartic acid, commonly used in peptide synthesis and organic chemistry. The "Boc" (tert-butyloxycarbonyl) group serves as a protective group for the amino function, allowing for selective reactions without interfering with the amine's reactivity. The "OtBu" (tert-butyl) group is a protecting group for the carboxylic acid, enhancing the stability and solubility of the compound. This substance typically appears as a white to off-white solid and is soluble in organic solvents such as dichloromethane and dimethyl sulfoxide. Its structure includes a chiral center, making it relevant in the synthesis of peptides with specific stereochemistry. Boc-D-Asp-OtBu is utilized in various applications, including drug development and the synthesis of biologically active compounds, due to its ability to facilitate the formation of peptide bonds while maintaining the integrity of the aspartic acid residue. Proper handling and storage are essential, as with many chemical substances, to ensure safety and stability.
