Description

cis-15-Octadecenoic Acid Methyl Ester is a high-purity monounsaturated fatty acid methyl ester (FAME) characterized by the cis configuration of its double bond at the 15th carbon. This specific structural isomer is a valuable intermediate and reference standard in organic synthesis and analytical chemistry. It serves critical roles in the production of specialty chemicals, advanced lubricants, and as a key building block for pharmaceutical and cosmetic actives. Industries requiring precise fatty acid derivatives for research, development, and manufacturing will find this ester essential for its defined composition and reliable performance.

Application

• Chemical Synthesis Intermediate: A crucial building block for synthesizing more complex lipid derivatives, surfactants, and specialty polymers.
• Analytical Reference Standard: Used in gas chromatography (GC) and mass spectrometry (MS) for the identification and quantification of fatty acid profiles in various matrices.
• Lubricant & Fuel Additive Precursor: Serves as a raw material for producing high-performance ester-based lubricants and biodiesel research.
• Pharmaceutical & Cosmetic Ingredient: Employed in the research and development of lipid-based drug delivery systems and emollients for personal care formulations.
• Biochemical Research: Used in studies of lipid metabolism, membrane biophysics, and as a substrate for enzymatic reactions.
• Food Science Research: Acts as a standard for analyzing food oils and fats to determine specific fatty acid compositions.
