I. [Product Description]
OPSS-PEG-SPDP is a multifunctional organic intermediate with dual reactive groups of ortho-pyridyldithio (OPSS) and N-hydroxysuccinimide ester of 3-(2-pyridyldithio) propionic acid (SPDP). It achieves precise coupling through a polyethylene glycol (PEG) segment with adjustable molecular weight. This compound can be used as an efficient catalyst or cross-linking agent and is widely used in the fields of biomacromolecule modification and polymer material synthesis.

II. [Product Details]
