Description

4,7,10,13,16-Nonadecapentaenoic Acid, Ethyl Ester, (4Z,7Z,10Z,13Z,16Z)- is a high-purity, long-chain polyunsaturated fatty acid (PUFA) ethyl ester derivative, identified by CAS No. 2692622-82-3. This compound is a critical intermediate and reference standard for advanced research in lipidomics, nutraceutical development, and the synthesis of specialized pro-resolving mediators (SPMs). It is essential for pharmaceutical R&D, academic institutions, and manufacturers focused on metabolic health, inflammation resolution, and high-value nutritional supplements.

Application

• Pharmaceutical Research Intermediate: A key building block for the synthesis of novel lipid-based therapeutics and pro-resolving mediators.
• Biochemical Reference Standard: Used in analytical laboratories for method development, calibration, and quantification in LC-MS and GC-MS lipid profiling.
• Nutraceutical Development: Serves as a precursor for high-purity ω-3 and other PUFA concentrates in dietary supplement formulations.
• Cell Culture & In Vitro Studies: Applied in biomedical research to study lipid metabolism, signaling pathways, and membrane fluidity.
• Cosmeceutical Actives: Incorporated into advanced skincare products targeting anti-inflammatory and barrier repair functions.
• Chemical Synthesis: Utilized in organic synthesis for creating complex, biologically active lipid molecules.

Quality Control

Every batch of 4,7,10,13,16-Nonadecapentaenoic Acid, Ethyl Ester is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, isomeric purity, and impurity profiles. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates and ISO standards for research chemicals.

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., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature before opening to minimize moisture condensation. Keep away from heat and ignition sources.
