Description

Methyl cis-5-Eicosenoate is a high-purity fatty acid methyl ester (FAME) characterized by its specific cis-configuration at the 5-position of a 20-carbon chain. This precise molecular structure makes it a valuable intermediate and reference standard for research and industrial synthesis. It is primarily utilized in the production of specialty chemicals, advanced lubricants, and as a critical component in lipidomics and metabolic studies. Industries requiring high-purity lipid derivatives for pharmaceuticals, cosmetics, and advanced material science rely on this compound for its consistency and quality.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized lipid-based drug molecules and prodrugs.
• Biochemical Research: Serves as a critical standard and reagent in lipidomics, metabolic pathway analysis, and membrane biophysics studies.
• Specialty Lubricants & Additives: Acts as a precursor or additive in formulating high-performance, biodegradable lubricants and functional fluids.
• Cosmetic & Personal Care Ingredients: Employed in the development of emollients, skin-conditioning agents, and other lipid-based formulations.
• Organic Synthesis Building Block: Utilized as a chiral starting material or intermediate for synthesizing complex natural products and fine chemicals.
• Food & Flavor Chemistry: Can be used as a reference compound or intermediate in the analysis and synthesis of flavor and fragrance components.
