Description

Octadecadienoic Acid is a high-purity unsaturated fatty acid, a key intermediate in the synthesis of specialized chemicals and advanced materials. Its value lies in providing a consistent and reliable source of a defined C18 diene structure for precise chemical modifications. This product is essential for manufacturers and R&D laboratories in the pharmaceutical, cosmetic, and specialty polymer industries seeking to develop innovative formulations.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring specific lipid moieties.
• Cosmetic & Personal Care Ingredient: Used in the formulation of high-end emollients, moisturizers, and skin barrier repair products due to its skin-compatible fatty acid profile.
• Specialty Polymer Synthesis: Acts as a monomer or co-monomer in creating polymers with tailored properties, such as flexibility, hydrophobicity, or biodegradability.
• Lubricant & Grease Additive: Employed as a precursor for synthesizing bio-based lubricant additives and metalworking fluid components.
• Research & Development: A valuable standard and reagent in biochemical and nutritional studies focused on lipid metabolism and fatty acid analysis.
• Surfactant & Detergent Precursor: Used to produce amphiphilic molecules for industrial and household cleaning applications.
