Description

(9Z,12Z)-Octadeca-9,12-Dienoic Acid, (Z)-Octadec-9-Enoic Acid is a high-purity, defined mixture of unsaturated fatty acids, primarily linoleic and oleic acids, identified by CAS No. 84789-96-8. This specific composition is critical for applications requiring consistent reactivity and predictable physical properties derived from its conjugated and non-conjugated double-bond systems. It serves as a versatile intermediate and functional ingredient for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries.

Application

• Pharmaceutical Intermediates: Used in the synthesis of lipid-based drug delivery systems, prodrugs, and active pharmaceutical ingredients (APIs) where specific fatty acid profiles are required.
• Cosmetic & Personal Care Formulations: Acts as an emollient, skin-conditioning agent, and base material for synthesizing esters in creams, lotions, and serums.
• Biochemical Research & Reagent: Serves as a standard or substrate in lipid metabolism studies, cell culture media supplementation, and enzymatic assays.
• Lubricant & Surfactant Synthesis: A key raw material for producing bio-based lubricants, metalworking fluids, and environmentally friendly surfactants.
• Polymer & Resin Modification: Used to introduce flexibility and alter curing properties in alkyd resins, polyesters, and other polymeric materials.
• Nutritional Supplements: Employed in the manufacture of specialized nutritional products and encapsulated lipid formulations.
