Folate-PEG2 acid CAS:848489-26-9 is a chemical compound that contains several functional groups, including a folate group and a PEG (polyethylene glycol) chain. The folate group can selectively bind to folate receptors that are overexpressed in certain cancer cells, allowing for targeted delivery of drugs or other molecules to these cells. The PEG chain improves the solubility, stability, and biocompatibility of the compound, while also serving as a flexible linker that allows for efficient conjugation of other molecules.
