I. [Product Description]
SPDP-PEG-SVA3-(2-pyridyldithio)propionic acid N-hydroxysuccinimide ester-polyethylene glycol-succinimidyl valerate is a multifunctional organic intermediate with both efficient cross-linking and controlled release properties. It is widely used in bioconjugation reactions and polymer material synthesis. The synergistic effect of the 2-pyridyldithio group and the NHS active ester in its structure makes it a key component in the preparation of pharmaceutical intermediates and catalyst support systems.
