PEG3-Bis-isothiocyanato (CAS:103144-38-3) is a small molecule drug with key functional groups: PEG3 and bis-isothiocyanato. PEG3 boosts solubility and stability, while bis-isothiocyanato enables chemical reactivity. Commonly used as a crosslinker for biomaterials like hydrogels and nanoparticles, it forms stable bonds with amine groups on biomolecules. The PEG3 spacer ensures selective crosslinking, reducing unwanted interactions with other cellular elements.
