mPEG3-SH (CAS NO.: 31521-83-2) is a PEG linker featuring a terminal thiol group. The thiol group enables selective conjugation with maleimides, gold surfaces, or other thiol-reactive groups, forming stable thioether bonds. This versatile compound is commonly used in bioconjugation, surface modification, and drug delivery applications due to its water solubility, biocompatibility, and reactive functionality.
Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
