2-[2-[2-[2-[2-(Benzyloxy)ethoxy]ethoxy]ethoxy]ethoxy]ethanol Chemical Properties,Uses,Production

Description

Benzyl-PEG6-alcohol is a PEG linker with a benzyl protecting group and a primary alcohol. The benzyl protecting group can be removed under acidic conditions. The primary alcohol can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.

Uses

BnO-PEG5-OH is a PEG-based PROTAC linker can be used in the synthesis of PROTACs.
