Description

2,5,8,10,13,16-Hexaoxaheptadecane is a high-purity polyether compound, also known as a specific polyethylene glycol (PEG) derivative. It serves as a versatile and effective crown ether analog and phase transfer catalyst, facilitating reactions between reagents in immiscible phases. This chemical is essential for manufacturers and R&D laboratories in the pharmaceutical, specialty chemical, and polymer synthesis sectors, where precise molecular interactions and solubility enhancement are critical.

Application

• Phase Transfer Catalyst (PTC): Enables reactions between ionic reagents in aqueous phases and organic substrates in organic solvents, improving yield and efficiency in alkylation and other synthesis steps.
• Polymer Synthesis & Modification: Acts as a chain extender, cross-linking agent, or hydrophilic segment in the production of polyurethanes, resins, and specialty polymers.
• Pharmaceutical Intermediate: Used in the synthesis of complex drug molecules where its ether structure can act as a solubilizing linker or functional group.
• Chemical Complexation Agent: Binds selectively with metal cations (e.g., alkali metals) in analytical chemistry and separation processes.
• Surfactant & Formulation Aid: Serves as a non-ionic surfactant or co-solvent in industrial formulations, coatings, and cleaning products.
• Electrolyte Additive: Investigated for use in battery electrolytes to improve ionic conductivity and stability.
• Research & Development: A valuable tool in academic and industrial R&D for studying host-guest chemistry and developing new catalytic systems.
