- Description
Br-PEG4-CH2CH2COOtBu is a PEG linker with four PEG units, a bromide group, and a tert-butyl-protected carboxyl group. The bromide provides a leaving group for nucleophilic substitution, allowing attachment to biomolecules or other substrates. Acidic removal of the tert-butyl protecting group exposes a carboxyl group for subsequent conjugation.
Also named Bromo-PEG4-t-butyl ester, this reagent is used in ADC synthesis and is cataloged among halide PEG reagents and ADC linkers. Its molecular formula is C15H29BrO6, molecular weight is 385.29, and listed purity is ≥95%.
