I. [Product Introduction]
DTPA-PEG-OPSS is a multifunctional organic intermediate with chelation coordination, biocompatibility, and controllable coupling properties. It is widely used in the synthesis of pharmaceutical intermediates and the modification of biomaterials. Its core value lies in achieving precise molecular cross-linking and functional design through the strong chelating ability of DTPA, the hydrophilicity of the PEG chain, and the high-efficiency thiol reactivity of the OPSS group. It can also be used as a catalyst carrier or reaction medium to optimize complex synthesis routes.
