- Description
OH-PEG4-CH2CH2COOtBu is a PEG linker bearing a hydroxyl group and a tert-butyl-protected carboxyl group. Its hydrophilic PEG spacer supports aqueous solubility for bioconjugation and synthetic work. The hydroxyl terminus can undergo further modification, while acidic deprotection of the tert-butyl ester exposes a free carboxylic acid.
The compound is used as a noncleavable linker in antibody-drug conjugate synthesis and can also be employed in PROTAC synthesis. Its listed molecular formula is C15H30O7, molecular weight is 322.39, and purity is ≥95%.
