Collection: PEG Phosphonic Acid

PEG Phosphonate represents a class of PEG derivatives in which a polyethylene glycol (PEG) chain is attached to a phosphonate group, either as a phosphonate ester or phosphonic acid. The organophosphorus moiety can form a robust bond with metal oxides, establishing a stable structure through phosphate metal coordination. This characteristic has garnered significant attention in the field of pharmaceutical research and development. PEG Phosphonate can be covalently attached to drugs or molecules and subsequently linked to proteins or peptides, facilitating the targeted delivery of therapeutic agents to specific tissues or cells. The phosphonate group's potent binding to metal ions, particularly calcium associated with diseased tissues or cells, is noteworthy. Additionally, PEG phosphonate linkers find applications in imaging and diagnostics, as the phosphonate group can chelate metal ions, enabling the creation of contrast agents for imaging techniques like MRI or PET.
