Description

17-Keto-7(Z),10(Z),13(Z),15(E),19(Z)-Docosapentaenoic Acid is a specialized, high-purity oxylipin derived from docosapentaenoic acid, distinguished by its unique keto group and conjugated double-bond system. This compound matters as a critical reference standard and bioactive intermediate for advanced research into lipid signaling pathways and inflammation modulation. It is essential for pharmaceutical R&D, academic biochemistry laboratories, and manufacturers of high-value nutraceuticals seeking to develop novel therapeutic agents.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis (HPLC, LC-MS) of related oxylipins in drug discovery and metabolic studies.
• Biochemical Research: Serves as a key substrate or inhibitor in enzymatic studies to investigate eicosanoid and docosanoid biosynthesis and function.
• Nutraceutical Development: Acts as a high-purity intermediate for the synthesis of specialized pro-resolving lipid mediators (SPMs) with potential anti-inflammatory properties.
• Cell Signaling Studies: Utilized in vitro and in vivo models to study the role of oxidized fatty acids in cellular communication, immune response, and resolution of inflammation.
• Analytical Chemistry: Employed as a calibration standard to develop and validate sensitive analytical methods for complex lipidomic profiles.

Quality Control

Every batch of 17-Keto-7(Z),10(Z),13(Z),15(E),19(Z)-Docosapentaenoic Acid is produced and analyzed under strict quality management systems. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with research and development standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container under an inert atmosphere (e.g., argon or nitrogen), protected from light. For long-term stability, store at -20°C or below. Allow the sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from oxidizing agents.
