Ethanol, 2-[2-(2-bromoethoxy)ethoxy]- Chemical Properties,Uses,Production

Description

Bromo-PEG3-alcohol is a PEG linker containing a bromide group with a terminal hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.

Uses

Br-PEG3-OH is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
