Tos-PEG3-Tos CAS:7460-82-4, a versatile bifunctional reagent, features a polyethylene glycol (PEG) spacer flanked by tosyl (Tos) groups. PEG, a hydrophilic and biocompatible polymer, enhances water solubility and bioavailability, while the tosyl groups enable selective functionalization. This unique combination offers flexibility for conjugation reactions in pharmaceutical research.
In pharmaceutical research and development, Tos-PEG3-Tos plays a pivotal role in drug conjugate synthesis. Its bifunctionality facilitates the attachment of active pharmaceutical ingredients (APIs) to carriers or targeting moieties, optimizing therapeutic efficacy and selectivity. Employing Tos-PEG3-Tos has significantly advanced the design of targeted drug delivery systems and bioconjugate therapies.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
