Application

3-Mercaptopropionic acid NHS ester serves as a reliable thiol-reactive crosslinking reagent, enabling site-specific conjugation under mild aqueous conditions. Its NHS ester moiety facilitates efficient coupling to primary amines on proteins, peptides, or surfaces, while the terminal thiol group allows for subsequent maleimide-based ligation or disulfide formation. Offers excellent bench stability and straightforward purification, making it well-suited for bioconjugation workflows requiring orthogonal functionalization.
