Description

6,9,12,15-Octadecatetraenoic Acid is a polyunsaturated fatty acid of significant biochemical interest. This compound matters as a key intermediate in the synthesis of specialized pro-resolving mediators (SPMs) and other bioactive lipid derivatives, which are crucial for research in inflammation and metabolic pathways. It is primarily needed by pharmaceutical R&D laboratories, nutraceutical formulators, and academic institutions focused on lipidomics and the development of novel therapeutic agents.

Application

• Pharmaceutical Research Intermediate: A critical building block for the synthesis of specialized pro-resolving lipid mediators (SPMs) like resolvins and protectins.
• Biochemical Standard & Reference Material: Used as a high-purity analytical standard in lipidomics, metabolomics, and gas chromatography/mass spectrometry (GC-MS) for accurate quantification.
• Nutraceutical & Dietary Supplement Development: Serves as a precursor in the research and formulation of advanced ω-3 and ω-6 fatty acid supplements with targeted bioactivity.
• Cell Culture & In Vitro Studies: Employed in cell-based assays to study the effects of polyunsaturated fatty acids on inflammation, cell signaling, and membrane fluidity.
• Cosmeceutical Research: Investigated for its potential anti-inflammatory and skin-barrier enhancing properties in advanced skincare formulations.
• Chemical Synthesis: Used as a starting material or intermediate in organic synthesis for creating novel compounds with potential therapeutic value.

Quality Control

Our 6,9,12,15-Octadecatetraenoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and GC-MS, to ensure high purity and identity confirmation. Certificates of Analysis (COA) detailing purity, impurities, and other critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep the container in a cool, dry, and well-ventilated area. Allow the product to reach room temperature before opening to minimize moisture condensation.
