Iodo PEG linkers are versatile chemical compounds that have found widespread use in the field of pharmaceutical research and development. These linkers are made up of polyethylene glycol (PEG) chains that are functionalized with an iodine atom. The introduction of functional groups onto these linkers can greatly enhance their efficacy in drug development. For example, iodo PEG linkers can be used to attach small molecules or peptides to larger protein molecules, allowing for the targeted delivery of drugs to specific cells or tissues. In addition, these linkers can also be used to modify the pharmacokinetic properties of drugs, such as their solubility or bioavailability. Overall, iodo PEG linkers represent a promising area of research in the development of novel drug delivery systems and therapies.
