I. [Product Description]
SPDP-PEG-Aldehyde is a multifunctional organic intermediate that combines the dynamic covalent bond properties of the pyridyl disulfide group with the efficient coupling ability of the aldehyde group. It can serve as an efficient cross-linking agent for bioconjugation reactions. Its structure contains an N-hydroxysuccinimide ester (NHS) active group, which enables amine-specific modification. Combined with a customizable molecular weight PEG chain, it significantly enhances water solubility and biocompatibility. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalytic reaction systems.
