Folate-PEG2-hydrazide CAS:1360447-64-8 is a small molecule linker that contains several functional groups, including a folate group, a PEG (polyethylene glycol) chain, and a hydrazide group. The folate group enables selective targeting of cancer cells that overexpress the folate receptor, which is highly expressed in many types of cancer cells but not in normal cells. The PEG chain improves the solubility and biocompatibility of the compound, while the hydrazide group can react with aldehydes or ketones to form stable hydrazone linkages, which can be used to attach the compound to other molecules. Overall, Folate-PEG2-hydrazide is a valuable tool for targeted drug delivery in cancer therapy, as it can improve the specificity and efficacy of treatment while minimizing toxicity to healthy cells.
