Description

3,7,11,15,19-Pentamethyl-2,6,10,14,18-Eicosapentaenoic Acid Ethyl Ester is a high-purity synthetic isoprenoid fatty acid ester, serving as a critical building block and reference standard in advanced chemical synthesis. This compound is valued for its precise molecular structure, which mimics natural polyisoprenoid chains, enabling research and development in specialized organic chemistry. It is primarily sought by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and specialty chemical sectors for applications requiring defined isoprenoid architecture.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the development of novel therapeutic agents, including retinoid analogs and lipid-based drug molecules.
• Nutraceutical Research: Used as a reference standard and precursor in the study and synthesis of advanced lipid supplements and fat-soluble vitamins.
• Specialty Polymer Synthesis: Acts as a monomer or chain extender in the creation of polymers with specific hydrophobic or biocompatible properties.
• Chemical Biology & Biochemistry: Employed as a tool compound to study lipid metabolism, protein-lipid interactions, and membrane biology.
• Flavor & Fragrance Industry: Potential use as an intermediate for synthesizing complex terpenoid-based aroma chemicals.
• Cosmetic Ingredient Research: Investigated for use in advanced skincare formulations targeting lipid barrier repair and stabilization.

Quality Control

Our production of 3,7,11,15,19-Pentamethyl-2,6,10,14,18-Eicosapentaenoic Acid Ethyl Ester adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP-compliant manufacturing for pharmaceutical applications and can tailor purity grades to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive). For long-term storage, consider inert gas purging to prevent oxidation. Keep away from strong oxidizing agents.
