Used extensively in peptide synthesis, this compound is a protected form of D-glutamic acid, with the α-amino group protected by Boc (tert-butoxycarbonyl), the side-chain γ-carboxylic acid as methyl ester (OMe), and the α-carboxylic acid as DCHA (dicyclohexylamine) salt. This ensures selective reactions during the assembly of peptide chains. The Boc group provides stability under various conditions, while the DCHA salt enhances solubility and handling. Commonly applied in the production of pharmaceuticals and bioactive peptides, especially in solid-phase synthesis, it plays a crucial role in the development of drugs targeting neurological disorders, cancer, and metabolic diseases. Additionally, it is utilized in research to study enzyme mechanisms and protein interactions due to its ability to maintain structural integrity during complex reactions.
