I. [Product Description]
OPSS-PEG-Mal is a multifunctional organic intermediate with dual reactive groups of ortho-pyridyl disulfide (OPSS) and maleimide (Mal). It can achieve efficient bioconjugation through thiol-disulfide exchange reaction and thiol click chemistry. Its core value lies in being used as a cross-linker or catalyst carrier, and it has broad application potential in the fields of biomaterial assembly, polymer modification, and nanosynthesis, especially suitable for the precise functional design of pharmaceutical intermediates.
