This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group acts as a temporary protecting group for the amine functionality during the synthesis process. The tert-butyl group protects the hydroxyl group of the tyrosine residue, preventing unwanted side reactions. The dimethyl modification on the tyrosine ring enhances steric hindrance, which can be useful in controlling peptide folding and interactions. This compound is especially valuable in the synthesis of complex peptides and proteins, where selective deprotection and precise sequence assembly are critical. It is commonly employed in research laboratories and pharmaceutical development for creating peptides with specific structural and functional properties.
