Description

cis-7,10,13,16,19-Docosa-Tetraenoic Acid Methyl Ester is a high-purity methyl ester derivative of a long-chain polyunsaturated fatty acid (PUFA), specifically a C22:4 n-3 isomer. This compound serves as a critical reference standard and synthetic intermediate for research and development in advanced lipid chemistry. It is essential for organizations requiring precise, well-characterized materials for analytical method development, biochemical studies, and the synthesis of complex lipid molecules. Target users include manufacturers in the pharmaceutical, nutraceutical, and advanced research sectors.

Application

• Pharmaceutical Reference Standard: Used for the identification, purity assessment, and quantification of ω-3 fatty acid derivatives in drug development and quality control (QC) laboratories.
• Biochemical Research: Serves as a substrate or precursor in studies of lipid metabolism, enzyme activity (e.g., desaturases, elongases), and cell signaling pathways.
• Nutraceutical R&D: Acts as a key intermediate in the synthesis and analysis of specialized, high-value lipid-based nutritional supplements.
• Analytical Chemistry: Employed as an internal or external standard in Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) for accurate fatty acid profiling.
• Organic Synthesis: Utilized as a building block for the preparation of more complex lipid conjugates, probes, or pharmaceutical agents.
• Food Science Research: Applied in studies investigating the stability, bioavailability, and health effects of specific polyunsaturated fatty acid isomers.

Quality Control

Every batch of our cis-7,10,13,16,19-Docosa-Tetraenoic Acid Methyl Ester is produced and tested under a strict quality management system. We employ advanced analytical techniques including GC, HPLC, and GC-MS to ensure identity, purity, and consistency. Our products are suitable for use as high-grade reference materials. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep the sealed container under an inert atmosphere (e.g., nitrogen or argon) at -20°C or below to minimize oxidation. Allow the product to reach room temperature in a desiccator before opening to prevent moisture condensation. Store away from strong oxidizers and heat sources.
