Description

Lysine, Phenylmethyl Ester CAS NO 2183491-55-4 is a protected amino acid derivative where the lysine side chain amine is safeguarded by a benzyl ester group. This chemical intermediate is critical for enabling selective peptide synthesis and modification in advanced research and pharmaceutical development. It is primarily needed by fine chemical manufacturers, peptide synthesis specialists, and R&D laboratories working on novel therapeutic agents and biochemical tools.

Application

• Peptide Synthesis Intermediate: Serves as a key building block for the solid-phase and solution-phase synthesis of complex peptides, allowing for the controlled incorporation of lysine residues.
• Pharmaceutical Research: Used in the development and production of peptide-based active pharmaceutical ingredients (APIs) and drug candidates.
• Bioconjugation Chemistry: Facilitates the site-specific modification of proteins, antibodies, and other biomolecules for diagnostic and therapeutic applications.
• Protecting Group Strategy: The benzyl ester protecting group is instrumental in multi-step organic syntheses where selective deprotection is required.
• Biochemical Tool Development: Employed in creating specialized probes, enzyme substrates, and inhibitors for biochemical and cellular studies.
• Material Science: Potential use in the synthesis of functionalized polymers and smart biomaterials.
