Used primarily in peptide synthesis as a protecting group for amino acids. It helps prevent unwanted side reactions during the formation of peptide bonds. Its trifluoroacetyl (TFA) group is easily removed under mild conditions, making it suitable for sensitive peptide sequences. Commonly applied in the production of pharmaceuticals and research peptides, ensuring high purity and yield. It is also utilized in the synthesis of complex organic molecules where selective protection of functional groups is required.
