Description

n-ε-Formyl-L-Lysine is a chemically modified derivative of the essential amino acid L-lysine, featuring a formyl group on its ε-amino side chain. This specific modification makes it a valuable intermediate and building block in advanced organic synthesis and peptide research. It is particularly sought after by researchers and manufacturers in the pharmaceutical and biotechnology sectors for the development of novel peptide-based therapeutics and biochemical tools.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex peptide drugs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a protected lysine derivative in solid-phase peptide synthesis (SPPS) and for studying enzyme-substrate interactions.
• Proteomics & Bioconjugation: Serves as a precursor for creating site-specifically modified proteins and antibody-drug conjugates (ADCs).
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for method development and validation.
• Nutritional Science Research: Used in studies investigating amino acid metabolism and the biological effects of modified amino acids.
