Description

Isopropyl (9Z,12Z,15Z)-9,12,15-Octadecatrienoate is a high-purity ester derivative of α-linolenic acid, a key ω-3 fatty acid. This compound is valued for its role as a versatile chemical intermediate and a functional ingredient in advanced formulations. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for research, synthesis, and product development requiring specific lipid profiles.

Application

• Pharmaceutical Intermediate: Used in the synthesis of lipid-based drug delivery systems, prodrugs, and active pharmaceutical ingredients (APIs).
• Nutraceutical & Dietary Supplement Formulation: Serves as a concentrated, esterified source of ω-3 (ALA) for encapsulation in softgels and liquid supplements.
• Biochemical Research & Standard: Acts as a reference standard in chromatography (HPLC, GC) and in metabolic pathway studies related to lipidomics.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its emollient properties and potential skin-barrier benefits.
• Specialty Lubricants & Additives: Utilized in the development of bio-based lubricants and functional fluid additives.
• Polymer & Material Science: Employed as a monomer or plasticizer in the creation of specialized polymers and coatings.
