Description

(4E,8E,11E,15E)-Octadeca-4,8,11,15-Tetraenoic Acid is a polyunsaturated fatty acid characterized by its four conjugated trans-double bonds. This specific stereochemistry makes it a valuable intermediate and reference standard for research in lipid biochemistry and synthetic organic chemistry. It is primarily sought by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced materials sectors for its role in studying lipid metabolism, signaling pathways, and as a building block for specialized compounds.

Application

• Biochemical Research: Used as a high-purity reference standard and intermediate in studies of fatty acid metabolism, enzyme activity (e.g., desaturases, elongases), and lipid signaling pathways.
• Pharmaceutical Development: Serves as a key synthetic precursor or an analytical standard in the development of drugs targeting lipid-related disorders and inflammatory conditions.
• Nutraceutical Research: Investigated for its potential biological activity and as a component in advanced lipid formulations for nutritional science.
• Organic Synthesis: Acts as a versatile building block for the synthesis of complex natural products, specialized lipids, and novel organic compounds due to its conjugated tetraene structure.
• Analytical Chemistry: Employed as a certified reference material (CRM) for calibrating instruments and validating analytical methods like HPLC and GC-MS in lipid analysis.
• Cosmeceutical Research: Explored for potential applications in skincare formulations targeting specific cellular functions, given the role of certain fatty acids in skin health.
