Description

trans-12-Octadecenoic Acid (C18:1,*(trans-12)) is a monounsaturated fatty acid characterized by a trans double bond at the 12th carbon. This specific geometric isomer is a valuable intermediate and reference standard for research and industrial synthesis, offering distinct chemical behavior compared to its cis-isomer counterparts. It is primarily utilized by researchers and manufacturers in the fields of lipid chemistry, material science, and specialty chemical production who require high-purity, well-defined fatty acid derivatives.

Application

• Biochemical & Pharmaceutical Research: Used as a critical reference standard and intermediate in lipidomics, metabolic pathway studies, and the synthesis of bioactive molecules.
• Specialty Chemical Synthesis: Serves as a key building block for producing surfactants, lubricant additives, and other oleochemical derivatives where the trans-configuration imparts specific physical properties.
• Material Science: Investigated for use in polymer modification and the creation of advanced materials with tailored thermal and mechanical characteristics.
• Analytical Standards: Essential for calibrating analytical instruments (GC, HPLC) to accurately identify and quantify trans-fatty acid isomers in complex matrices like food and biological samples.
• Nutritional Science: Employed in controlled studies to understand the metabolic effects and health impacts of specific trans-fatty acid isomers.
