Description

12-Octadecenoic Acid Chloride is a high-purity, unsaturated fatty acid chloride derivative, also known as oleoyl chloride. This reactive intermediate is essential for introducing the long-chain oleoyl moiety into target molecules, enabling the synthesis of specialized esters, amides, and polymers. It is a critical raw material for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop products with specific hydrophobic or self-assembling properties.

Application

• Pharmaceutical Intermediates: Key building block for synthesizing prodrugs, lipid conjugates, and active pharmaceutical ingredients (APIs) requiring lipophilic modification for enhanced bioavailability.
• Agrochemical Synthesis: Used in the production of specialized herbicides, fungicides, and plant growth regulators where the oleoyl chain influences penetration and activity.
• Polymer & Resin Modification: Serves as a monomer or modifier in the creation of polyamides, polyesters, and alkyd resins to impart flexibility, water repellency, or specific functional groups.
• Surfactant & Emulsifier Production: Reacted with amines or alcohols to manufacture non-ionic and cationic surfactants for cosmetics, detergents, and industrial formulations.
• Lubricant & Fuel Additives: Employed in synthesizing ester-based additives that improve lubricity, reduce wear, and act as corrosion inhibitors.
• Bioconjugation & Research Chemicals: Utilized in biochemical research for lipid tagging, protein modification, and the synthesis of fluorescent probes or diagnostic agents.

Quality Control

Our 12-Octadecenoic Acid Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, impurity profile analysis, and identity confirmation, to ensure it meets precise specifications for reactivity and purity. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with agreed-upon standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
