I. [Product Description]
NHS-PEG-Estrogen is a polyethylene glycol-estrogen conjugate modified with N-hydroxysuccinimide ester active groups. It can be used as an organic intermediate in the coupling reaction of biological macromolecules or as a highly efficient catalyst in the synthesis of pharmaceutical intermediates. Its structure combines the hydrophilicity of the PEG segment and the specific binding ability of estrogen derivatives, making it suitable for the construction of precise coupling systems.

II. [Product Details]
