Description

N2,N2-Dimethyl-N6-(1-Oxooctadecyl)-L-Lysine is a chemically modified amino acid derivative, specifically a lysine amide with a long-chain fatty acyl group. This compound matters for its role as a key intermediate in the synthesis of specialized surfactants, emulsifiers, and bioactive conjugates, offering a unique combination of a polar amino acid head and a lipophilic tail. Industries that need it include pharmaceutical research for drug delivery systems, personal care for formulating mild and substantive conditioning agents, and specialty chemicals for creating novel amphiphilic structures. Its precise structure allows for targeted modification of surface activity and biocompatibility.

Application

• Pharmaceutical Intermediate: Used in the research and development of prodrugs and peptide-lipid conjugates for enhanced drug delivery and bioavailability.
• Personal Care Surfactant: Serves as a mild, cationic conditioning agent and emulsifier in hair care and skincare formulations, providing substantivity and softness.
• Bioconjugation Chemistry: Acts as a linker or building block for attaching lipid moieties to peptides, proteins, or other biomolecules in biochemical research.
• Specialty Emulsifier: Employed in the formulation of complex emulsions for agrochemicals, coatings, or industrial applications requiring stable oil-in-water systems.
• Biomimetic Membrane Studies: Utilized in research to synthesize lipidated amino acids for studying membrane-protein interactions and creating synthetic vesicles.
• Cosmetic Active Ingredient: Potential use as a skin-conditioning agent or delivery vehicle for active ingredients in cosmetic products.

Quality Control

Our N2,N2-Dimethyl-N6-(1-Oxooctadecyl)-L-Lysine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets precise specifications for research and industrial use. Certificates of Analysis (COA) detailing all test results are available upon request. We can support development projects requiring compliance with relevant ICH guidelines for impurities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This compound may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed in a dry environment to maintain stability and purity.
