Description

L-Tyrosine, n-[(1,1-Dimethylethoxy)Carbonyl]-o-Propyl- is a protected derivative of the essential amino acid L-Tyrosine, featuring a tert-butoxycarbonyl (Boc) protecting group on the amine and a propyl ester on the carboxylic acid. This compound is a critical building block in peptide synthesis and pharmaceutical research, offering enhanced stability and controlled reactivity during complex chemical processes. It is primarily needed by pharmaceutical R&D laboratories, peptide synthesis specialists, and fine chemical manufacturers developing novel therapeutic agents and bioactive molecules.

Application

• Peptide Synthesis: Serves as a key protected intermediate in solid-phase and solution-phase peptide synthesis (SPPS).
• Pharmaceutical Research: Used in the development and production of peptide-based drugs and active pharmaceutical ingredients (APIs).
• Bioconjugation: Acts as a modified amino acid for creating labeled peptides or protein conjugates for diagnostic and research purposes.
• Chemical Biology: Employed in the study of protein structure, function, and protein-protein interactions.
• Fine Chemical Manufacturing: A valuable intermediate for synthesizing more complex, tyrosine-containing organic molecules.
