Description

All-cis-4,7,10,13,16-Docosapentaenoic Acid Ethyl Ester is a high-purity ethyl ester derivative of the ω-3 fatty acid DPA (n-3), serving as a critical intermediate and reference standard for advanced nutritional and pharmaceutical research. This compound is valued for its defined chemical structure, which facilitates precise formulation and bioavailability studies in the development of specialized lipid-based products. It is essential for manufacturers and R&D laboratories in the nutraceutical, pharmaceutical, and biochemical sectors requiring a consistent, high-quality source of this specific long-chain polyunsaturated fatty acid ester.

Application

• Pharmaceutical Intermediates: Used as a key building block in the synthesis of advanced lipid-based drug formulations and active pharmaceutical ingredients (APIs).
• Nutraceutical & Dietary Supplement Production: Incorporated into high-end ω-3 supplements, specifically targeting formulations enriched with DPA (n-3) for enhanced health benefits.
• Biochemical Research & Reference Standards: Serves as a pure analytical standard for chromatography (HPLC, GC) and in metabolic pathway studies related to ω-3 fatty acids.
• Functional Food & Beverage Fortification: Employed in the enrichment of foods and beverages where a concentrated, esterified form of DPA is required for stability and efficacy.
• Cosmeceutical Ingredients: Utilized in the development of advanced skincare products for its potential anti-inflammatory and skin-barrier enhancing properties.
• Cell Culture & Biomedical Studies: Applied in *in vitro* studies to investigate the effects of specific fatty acid esters on cell membrane fluidity and signaling pathways.

Quality Control

Our All-cis-4,7,10,13,16-Docosapentaenoic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets stringent specifications for research and production use. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and physical characteristics is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below for long-term stability. For short-term use, storage at 2-8°C is acceptable. This material is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Keep the container tightly sealed in a dry and well-ventilated place.
