Description

Cholesteryl Docosapentaenoate is a high-purity, synthetic cholesterol ester of docosapentaenoic acid (DPA). This specialized lipid compound is valued for its role as a critical reference standard and a key intermediate in advanced lipidomics research and pharmaceutical development. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and life science sectors who require precise, well-characterized molecules for analytical calibration, metabolic studies, and the formulation of lipid-based delivery systems.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantification of cholesterol esters in biological samples via HPLC, GC-MS, and LC-MS.
• Lipidomics & Metabolic Research: A vital tool for studying lipid metabolism, membrane biophysics, and the biological roles of specific polyunsaturated fatty acid (PUFA) esters.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of more complex lipid-based drug candidates and prodrugs.
• Biomimetic Membrane Studies: Used in the formulation of liposomes and artificial membranes to model cell behavior and study drug-membrane interactions.
• Nutraceutical R&D: Employed in the development and analysis of advanced dietary supplements targeting cardiovascular and neurological health.
• Diagnostic Reagent Manufacturing: A component in the production of calibrators and controls for clinical diagnostic assays measuring lipid profiles.

Quality Control

Our Cholesteryl Docosapentaenoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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 product to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
