Bromo-PEG4-acid Chemical Properties,Uses,Production

Description

Bromo-PEG4-acid is a PEG linker containing a bromide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

Uses

Bromo-PEG4-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
