Description

cis-11-Octadecenoic Acid Methyl Ester is a high-purity fatty acid methyl ester (FAME) characterized by a specific cis-configuration at the 11th carbon. This compound serves as a critical intermediate and reference standard in the synthesis of fine chemicals, pharmaceuticals, and advanced lipid research. It is essential for industries requiring precise molecular structures, such as specialty polymer manufacturing, bio-lubricant formulation, and the development of active pharmaceutical ingredients (APIs).

Application

• Chemical Synthesis Intermediate: A key building block for producing complex organic molecules, including surfactants, plasticizers, and specialty esters.
• Pharmaceutical Research: Used as a reference standard and precursor in the development of lipid-based drug delivery systems and active pharmaceutical ingredients (APIs).
• Biofuel & Lubricant Research: Acts as a model compound for studying the properties and performance of biodiesel blends and synthetic bio-lubricants.
• Analytical Standard: Employed in gas chromatography (GC) and mass spectrometry (MS) for the identification and quantification of fatty acid profiles in various matrices.
• Specialty Polymer Production: Utilized in the synthesis of polymers with specific flexibility and hydrophobic characteristics.
• Cosmetic & Personal Care Ingredients: Serves as an emollient or conditioning agent in high-end cosmetic formulations.
