Description

8-Octadecenoic Acid Methyl Ester is a monounsaturated fatty acid methyl ester (FAME) derived from oleic acid. This compound serves as a versatile chemical intermediate and a model compound for studying lipid chemistry and biodiesel properties. It is essential for manufacturers and R&D laboratories in the oleochemical, biofuel, and specialty chemical sectors seeking high-purity lipid standards or reactive intermediates for synthesis.

Application

• Chemical Intermediate: A key starting material for synthesizing surfactants, lubricant additives, and plasticizers.
• Biofuel Research: Used as a reference standard and model compound in biodiesel formulation and quality analysis studies.
• Oleochemical Production: Serves as a precursor in the manufacture of fatty alcohols, amides, and other oleochemical derivatives.
• Analytical Standard: Employed as a high-purity standard in Gas Chromatography (GC) and other analytical methods for lipid profiling.
• Pharmaceutical & Cosmetic Excipient: Utilized in the development of drug delivery systems and as an emollient in cosmetic formulations.
• Polymer & Resin Modifier: Acts as a reactive diluent or modifier in the production of specialty polymers and coatings.

Quality Control

Our 8-Octadecenoic Acid Methyl Ester is produced under a rigorous quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and composition. A comprehensive Certificate of Analysis (COA) detailing purity (by GC), isomer content, and physical constants is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon). Keep away from heat, sparks, and open flame.
