Description

15-Methyl-2,5,8,11,14-Pentaoxahexadecane is a high-purity polyether compound, specifically a polyethylene glycol (PEG) derivative with a methyl-capped end group. This chemical is valued for its role as a versatile intermediate and solvent, offering a favorable balance of hydrophilicity and controlled reactivity. It is primarily utilized in the synthesis of specialty polymers, as a phase-transfer catalyst, and in the formulation of advanced materials for industries including pharmaceuticals, agrochemicals, and electronics.

Application

• As a solvent and reaction medium for organometallic chemistry and polymerization processes.
• As a key intermediate in the synthesis of non-ionic surfactants and specialty polymers.
• As a phase-transfer catalyst (PTC) in biphasic organic synthesis reactions.
• In the formulation of specialty coatings, adhesives, and sealants requiring controlled hydrophilicity.
• As a building block for dendrimers and other complex macromolecular architectures.
• In agrochemical formulations as a solvent or adjuvant to enhance efficacy.
• For research and development in material science, particularly for creating tunable polymeric networks.
• Potential use in electrolyte formulations for battery and capacitor applications.
