Description

N6-Benzylidene-L-Lysine CAS NO 14511-39-8 is a chemically modified derivative of the essential amino acid L-Lysine, featuring a benzylidene protecting group on its ε-amino function. This modification is critical for enabling selective peptide synthesis and protecting specific reactive sites during complex organic transformations. It serves as a valuable chiral building block and intermediate for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors, particularly in the development of novel peptide-based therapeutics and biochemical tools.

Application

• Pharmaceutical Intermediate: Key chiral synthon in the research and production of peptide drugs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a protected amino acid derivative in solid-phase peptide synthesis (SPPS) and other advanced organic synthesis methodologies.
• Fine Chemical Synthesis: Acts as a specialized building block for creating complex molecules with specific stereochemistry for agrochemicals and advanced materials.
• Protecting Group Chemistry: The benzylidene group provides a reversible protective function for the lysine side chain, enabling multi-step synthetic sequences.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our N6-Benzylidene-L-Lysine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific impurities is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment to prevent degradation and clumping. Handle with standard laboratory precautions.
