Description

15-Tetracosenoic Acid, (15E)- is a high-purity, monounsaturated very long-chain fatty acid (VLCFA) with the CAS number 115863-91-7. This compound serves as a critical building block and reference standard in advanced organic synthesis and lipid biochemistry research. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical sectors who require precise, well-characterized lipid intermediates for developing novel therapeutics, bioactive compounds, and high-performance materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex lipid-based drug molecules, prodrugs, and bioactive conjugates.
• Biochemical Research: Serves as a critical standard and precursor in lipidomics studies, membrane biophysics, and enzyme (e.g., elongase, desaturase) activity assays.
• Reference Standard: Employed as a high-purity analytical standard for chromatography (GC, HPLC) to identify and quantify similar fatty acids in complex biological or industrial samples.
• Specialty Chemical Synthesis: Acts as a key starting material for producing surfactants, lubricant additives, and specialty polymers with unique properties derived from its long carbon chain.
• Cosmetic & Nutraceutical Ingredient Development: Investigated for use in advanced skincare formulations and as a precursor for lipid-based nutrient carriers.
