This chemical is primarily used in peptide synthesis as a protecting group for histidine residues. It helps prevent unwanted side reactions during the formation of peptide bonds, ensuring the integrity and specificity of the peptide sequence. The DCHA (dicyclohexylamine) salt form enhances its stability and solubility, making it easier to handle in organic synthesis processes. It is particularly valuable in the production of complex peptides and proteins for pharmaceutical research and development.
