Thiol-PEG-CH2COOH (MW 2000)

Thiol-PEG-CH2COOH (MW 2000) is a heterobifunctional PEG linker used in constructing PROTAC molecules for targeted protein degradation. Its reactive thiol and carboxyl groups enable conjugation to warheads and E3 ligase ligands, facilitating the development of degraders for in vitro and in vivo cancer and disease research.
