Product Description:
L-Aspartic acid dibenzyl ester p-toluenesulfonate salt is widely used in organic synthesis, particularly in peptide chemistry. It serves as a protected form of L-aspartic acid, allowing selective reactions at other functional groups without affecting the carboxyl group. This compound is valuable in the synthesis of peptides and proteins, where it helps in the controlled incorporation of aspartic acid residues. Additionally, it is utilized in the preparation of chiral building blocks for pharmaceuticals, enabling the production of enantiomerically pure compounds. Its stability and ease of deprotection make it a preferred choice in complex synthetic pathways.
