Thiol-PEG-CH2COOH (MW 3400)

Thiol-PEG-CH2COOH (MW 3400) is a heterobifunctional polyethylene glycol linker commonly used in the synthesis of PROTAC molecules. Its reactive thiol and carboxyl groups enable conjugation to warheads and E3 ligase ligands, facilitating the development of targeted protein degraders for in vitro and in vivo research applications.
