Description

4(Z),7(Z),10(Z),13(Z),16(Z)-Nonadecapentaenoic Acid CAS NO 136156-13-3 is a highly unsaturated long-chain fatty acid characterized by five cis-configured double bonds. This specific polyunsaturated structure makes it a valuable intermediate and reference standard for research in lipid biochemistry and metabolic studies. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors.

Application

• Biochemical Research: Serves as a critical reference standard and substrate for studying fatty acid metabolism, desaturase enzyme activity, and eicosanoid biosynthesis pathways.
• Pharmaceutical Intermediates: Used in the synthesis of specialized lipid-based drug candidates and bioactive molecules targeting inflammatory and metabolic disorders.
• Nutraceutical Development: Acts as a precursor or model compound for developing advanced dietary supplements and functional food ingredients focused on lipid nutrition.
• Analytical Chemistry: Employed as a high-purity calibration standard in chromatographic (GC, HPLC) and mass spectrometric analyses for accurate quantification of complex lipid mixtures.
• Cosmetic Science: Investigated for potential use in advanced skincare formulations targeting skin barrier function and cellular signaling.

Quality Control

Our 4(Z),7(Z),10(Z),13(Z),16(Z)-Nonadecapentaenoic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee reliable and reproducible performance for your critical research and production 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., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake and thermal stress.
