SPDP-PEG4-acid

Overview

SPDP-PEG4-Acid (CAS: 581065-97-6) is a bifunctional PEG-based linker with an SPDP group for thiol coupling and a carboxylic acid for amine conjugation. Its PEG4 spacer enhances solubility and reduces steric hindrance, making it ideal for bioconjugation, PROTAC synthesis, and targeted drug development.
