Bromo-PEG4-CH2COOtBu Chemical Properties,Uses,Production

Description

Bromo-PEG4-CH2CO2tBu is a PEG linker containing a bromide group and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

Uses

Br-PEG4-CH2-Boc is a PEG- and Alkyl/ether-based PROTAC linker can be used in the synthesis of PROTACs[1].

IC 50

PEGs; Alkyl/ether
