Cas no 57461-34-4 (L-Asparagine methyl ester hydrochloride)
L-Asparagine methyl ester hydrochloride is a derivative of the amino acid L-asparagine, modified with a methyl ester group and hydrochloride salt. This compound is primarily used in peptide synthesis and biochemical research, where it serves as a protected form of asparagine to prevent unwanted side reactions. The hydrochloride salt enhances solubility in aqueous and organic solvents, facilitating its incorporation into complex molecular structures. Its stability and high purity make it suitable for applications in pharmaceutical development and enzymatic studies. The esterification also allows for selective deprotection, enabling controlled modifications in synthetic pathways. This reagent is valued for its reliability in producing well-defined peptide sequences.
