Description

Methyl (9Z,12E)-Octadeca-9,12-Dienoate is a high-purity fatty acid methyl ester (FAME) derivative, specifically the methyl ester of a conjugated linoleic acid (CLA) isomer. This compound serves as a critical chemical intermediate and reference standard for research and industrial synthesis. It is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and specialty chemical sectors requiring precise, high-quality building blocks for lipid-based products.

Application

• Pharmaceutical Intermediate: Used in the synthesis of bioactive lipid molecules and prodrugs for targeted drug delivery systems.
• Nutraceutical & Dietary Supplement Research: Acts as a key reference standard and precursor in the study of conjugated linoleic acid (CLA) isomers and their metabolic effects.
• Biochemical Research: Employed as a substrate or standard in lipidomics, metabolic pathway studies, and enzyme activity assays.
• Specialty Chemical Synthesis: Serves as a versatile building block for producing surfactants, emulsifiers, and other functional oleochemicals.
• Cosmetic & Personal Care Ingredients: Utilized in the development of emollients and skin-conditioning agents with specific fatty acid profiles.
• Analytical Standard: Provides a high-purity standard for gas chromatography (GC) and mass spectrometry (MS) analysis in quality control and research laboratories.
