Description

trans-11-Octadecenoic Acid is a monounsaturated fatty acid of significant industrial and research interest. Its specific geometric isomerism, with the double bond in the trans configuration at the 11th carbon, makes it a valuable intermediate and reference standard. This compound is essential for manufacturers and R&D teams in the chemical synthesis, lipid research, and specialty materials sectors seeking high-purity fatty acid derivatives.

Application

• Chemical Synthesis Intermediate: Used in the production of specialized surfactants, lubricant additives, and other oleochemical derivatives.
• Biochemical & Lipid Research: Serves as a critical reference standard and precursor in studies of fatty acid metabolism, membrane biophysics, and the biological effects of trans fatty acids.
• Analytical Standard: Employed as a high-purity calibrant in gas chromatography (GC) and mass spectrometry (MS) for the accurate quantification and identification of fatty acid profiles.
• Specialty Material Production: Acts as a building block for synthesizing advanced polymers, coatings, and bio-based materials requiring specific fatty acid structures.
• Nutritional Science Studies: Utilized in research to investigate the impact of specific trans-isomer fatty acids on health and metabolism.
