Benzyl-PEG-Tos

Benzyl-PEG-Tos, also known as benzyl-terminated polyethylene glycol tosylate, is a polymer that contains several functional groups, including a benzyl group, a polyethylene glycol (PEG) chain, and a tosylate group. This polymer has been widely used in pharmaceutical research and development due to its ability to improve the solubility and bioavailability of poorly soluble drugs. The PEG chain helps to increase the water solubility of the drug, while the tosylate group can be used to create a prodrug that can be activated in vivo by hydrolysis. Additionally, the benzyl group can be used as a linker to attach the polymer to a drug molecule, which can improve the drug’s pharmacokinetics and targeting capabilities.
