Description

Eicosenoic Acid CAS NO 26764-41-0 is a monounsaturated fatty acid, specifically a C20:1 ω-9 fatty acid, valued for its role as a versatile chemical intermediate and a component of specialty lipid formulations. Its unique long-chain structure makes it a critical building block for synthesizing high-value derivatives used in advanced materials and personal care. This product is essential for manufacturers in the oleochemical, pharmaceutical, and specialty chemical industries seeking a reliable, high-purity raw material for research and production.

Application

• Oleochemical Intermediates: A key raw material for producing esters, amides, and other derivatives used in lubricants, plasticizers, and surfactants.
• Pharmaceutical & Nutraceutical Synthesis: Serves as a precursor in the synthesis of bioactive lipids, prodrugs, and specialized fatty acid conjugates.
• Personal Care & Cosmetics: Incorporated into formulations for emollients, moisturizers, and specialty soaps due to its skin-conditioning properties.
• Research & Development: Used as a standard or reagent in lipidomics, metabolic studies, and biochemical research.
• Specialty Polymers: Acts as a monomer or modifier in the production of polyamides, polyesters, and other polymers requiring specific hydrophobic characteristics.
• Food-Grade Additives: Potential use in the synthesis of food-grade emulsifiers and release agents, subject to appropriate purity grades and regulatory compliance.

Quality Control

Our Eicosenoic Acid is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed purity and impurity profiles. For customers with specific regulatory needs, we can support documentation for compliance with standards such as REACH, FDA (where applicable), and cGMP for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 2-8°C for long-term stability. This product is easily oxidized (store under inert atmosphere). Allow the container to reach ambient temperature before opening to minimize moisture condensation.
