CAS 4792-15-8: Pentaethylene glycol

Pentaethylene glycol is a surfactant that is used in the formulation of topical products. It has been shown to have high values (i.e., low surface tension) in a model system, and it has been used to reduce the thermal expansion coefficient by forming a monolayer at the interface with water. Trifluoroacetic acid is added as an impurity to reduce the melting point and increase the solubility of pentaethylene glycol. Pentaethylene glycol has been used as a solvent for polymers, such as polyvinyl chloride, polystyrene, and polypropylene, but can also be found in pharmaceuticals such as anti-diarrheal agents or eye drops. Pentaethylene glycol is also used as surfactant in some biological samples, including blood serum and urine. It has been shown to inhibit bacterial growth when present at concentrations of 1%.

Pentaethylene glycol (3,6,9,12-Tetraoxatetradecane-1,14-diol) is a PROTAC linker belonging to the PEG class, which can be used to synthesize PROTAC molecules.

Pentaethylene glycol is used as an intermediate in the synthesis of cyclic and noncyclic polyethers, complexing agents and immobilized phase-transfer catalysts. It acts as a catalyst for potassium hydroxide induced elimination reactions in benzene. Further, it is used in functional fluids and viscosity adjustors.

Pentaethylene glycol

Applications Pentaethylene glycol is part of a group of compounds called polyethylene glycols (PEGs), which are major byproducts of non-ionic surfactants biodegradation. Pentaethylene glycol is a useful synthetic intermediate, and is used as a reagent to synthesize macrocyclic oligoesters through lipase-catalysis. References Hilker, I., et al.: Eur. Polym.
