This chemical is primarily utilized in the synthesis of peptides and amino acid derivatives. It serves as a protected form of L-aspartic acid, enabling controlled reactions in peptide bond formation without unwanted side reactions. The tert-butyl and tert-butoxycarbonyl (Boc) groups act as protective groups, which can be selectively removed under mild acidic conditions, allowing for further modifications or elongation of the peptide chain. Its dicyclohexylamine salt form enhances stability and solubility, making it suitable for use in organic synthesis and pharmaceutical research. This compound is particularly valuable in the production of complex peptides, including those with therapeutic applications, such as hormone analogs or enzyme inhibitors.
