Description

Dioctadecenyl-4,18-Dioxo-5,8,11,14,17-Pentaoxahenicosanedioic Acid is a high-purity, synthetic organic compound with a complex, long-chain structure featuring multiple ether and carboxylic acid functionalities. This unique molecular architecture makes it a valuable intermediate for the synthesis of specialized polymers, surfactants, and lubricant additives, where its bifunctional nature and hydrophobic chains are critical. It is primarily sought by R&D chemists and process engineers in the advanced materials, specialty chemicals, and performance additive sectors for developing novel formulations with enhanced properties.

Application

• Polymer Synthesis: Acts as a difunctional monomer or chain extender for producing polyesters, polyethers, and other specialty polymers with tailored flexibility and hydrophobicity.
• Surfactant & Emulsifier Intermediate: Used to synthesize non-ionic surfactants and emulsifiers for industrial cleaning formulations, agrochemicals, and coatings.
• Lubricant & Fuel Additive Precursor: Serves as a key building block for manufacturing high-performance viscosity modifiers, dispersants, and anti-wear additives.
• Cosmetic & Personal Care Ingredients: Employed in the synthesis of emollients, thickeners, and delivery agents for skin care products.
• Pharmaceutical Intermediates: Utilized in research for creating prodrugs or drug delivery systems due to its biocompatible linker potential.
• Adhesive & Sealant Formulations: Incorporated to modify rheology and improve the adhesion properties of high-end sealants and adhesives.
