Description
DL-asparagine is a racemic mixture of the non-essential amino acids, L and D-aparagine. It is generally used in growth-media for bacteria-growth. DL-Asparagine monohydrate can also be used to synthesize other salts such as DL-asparaginium perchlorate, DL-asparaginium nitrate and dimethyl DL-aspartate.
Application
DL-Asparagine serves as a versatile building block in peptide synthesis and metabolic pathway studies, offering stable amide functionality and well-documented reactivity in standard coupling protocols. Its zwitterionic nature enhances solubility in aqueous and polar organic media, facilitating handling and purification. Functions reliably in both solid-phase and solution-phase syntheses, enabling efficient incorporation into bioactive peptides and protein analogs.
