Isothiocyanato-PEG-Azide is a class of organic molecules that are widely used in pharmaceutical research and development. These molecules contain multiple functional groups, including an isothiocyanate group, a polyethylene glycol (PEG) linker, and an azide group. The isothiocyanate group is highly reactive and can be easily modified with other functional groups, while the PEG linker imparts solubility and biocompatibility to the molecule. The azide group is a commonly used bioorthogonal functional group, which allows for selective conjugation with other molecules in complex biological systems. These properties make Isothiocyanato-PEG-Azide an attractive tool for drug discovery, as it can be used to create bioconjugates for targeted drug delivery or imaging applications.
