Description

L-Lysine, 4-Oxo- (9Ci) is a chemically modified derivative of the essential amino acid L-lysine, characterized by the introduction of a ketone group at the 4-position. This specific structural modification makes it a valuable chiral building block and intermediate for advanced organic synthesis and pharmaceutical research. It is primarily utilized by research institutions and industrial R&D departments focused on developing novel bioactive compounds, peptide mimetics, and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for metabolic and neurological targets.
• Peptidomimetic Research: Used in the design and synthesis of peptide analogs and mimetics to enhance stability, bioavailability, or receptor selectivity.
• Biochemical Research: Acts as a precursor or standard in metabolic pathway studies and enzyme inhibition assays.
• Fine Chemical Synthesis: Employed as a specialized building block for the production of complex organic molecules in agrochemical and material science research.
• Reference Standard: Used as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our L-Lysine, 4-Oxo- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
