Description

9,12-Octadecadienoic Acid (Z,Z)-, Methyl Ester, Oxidized is a chemically modified derivative of methyl linoleate, a key fatty acid ester. This oxidized form is significant for its enhanced reactivity and functional properties, making it a valuable intermediate in advanced chemical synthesis. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries for applications requiring modified fatty acid backbones.

Application

• Polymer & Resin Modification: Acts as a reactive monomer or plasticizer intermediate to modify the flexibility and oxidative stability of polymers.
• Lubricant & Grease Formulation: Serves as a precursor for synthesizing specialized esters used in high-performance lubricants and metalworking fluids.
• Surface Coating & Ink Production: Utilized in the manufacture of alkyd resins and other binders for paints, varnishes, and printing inks.
• Chemical Intermediate: A key building block for further chemical transformations, including epoxidation, amidation, and sulfonation reactions.
• Research & Development: Used in academic and industrial R&D for studying lipid oxidation, polymer science, and new material development.

Quality Control

Our production of 9,12-Octadecadienoic Acid (Z,Z)-, Methyl Ester, Oxidized adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in composition, peroxide value, and other critical parameters. Certificates of Analysis (COA) documenting purity, identity, and key specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize further oxidation. Keep away from heat, sparks, and open flame.
